Consider a circuit-switching scenario in which Ncs users, must share a link of capacity 150 Mbps. Each user alternates between periods of activity when the user generates data at a constant rate of 20 Mbps and periods of inactivity when he generates no data. Suppose further that he is active only 20% of the time. Assume a circuit switched TDM. What is the maximum number of circuit-switched users that can be supported? Assume packet switching is used for the remaining parts of this question. Suppose there are 13 packet- switching users (i.e., Nps = 13). Can this many users be supported under circuit-switching? Explain. What is the probability that a given (specific) user is transmitting, and the remaining users are not transmitting? What is the probability that one user (any one among the 13 users) is transmitting, and the remaining users are not transmitting? When one user is transmitting, what fraction of the link capacity will be used by this user? What is the probability that any 7 users (of the total 13 users) are transmitting and the remaining users are not transmitting? (Hint: you will need to use the binomial distribution.) What is the probability that more than 7 users are transmitting? Comment on what this implies about the number of users supportable under circuit switching and packet switching. What is the probability that more than 7 users are transmitting? Comment on what this implies about the number of users supportable under circuit switching and packet switching.

I am struggling to write a python script that calculates the average length ,max length shortest length and overall average length of of a snake and ladder game. I use python 3
The length is the number the dice is rolled until the max is reached

We need a python script that calculates the number of moves it will take for a single player to reach 100. We have to simulate a snake and ladder game using python language. So one person plays the game several times and will compare the number of moves per each played game for us to be able to come up with the required data

describe and discuss the Software Development Life Cycle as it relates to creating software that will calculate the totals and dispense change for a cash register at a local grocery store

Ask the user to enter test scores. Once they have entered -1, print out the highest grade. Ensure that the grade entered is an integer.(Using Java Language)

Enter integers between 0 and 100, -1 when finished.

Enter a test score: [asdf]

Enter an integer.

Enter a test score: [32.5]

Enter an integer.

Enter a test score: [42]

Enter a test score: [99]

Enter a test score: [87]

Enter a test score: [x]

Enter an integer.

Enter a test score: [-1]

The max grade is: 99

For your program, you will choose either the Selection Sort algorithm or the Insertion Sort algorithm and create a recursive implementation of that algorithm. Your program should:

1. Randomly generate an array of at least 20 values.
2. Display the contents of that (unsorted) array.
3. Use the recursive implementation of either Selection or Insertion Sort to sort the values.
4. Display the contents of the now sorted array, to demonstrate the success of the algorithm.

In C language

Write a program that includes a function search() that finds the index of the first element of an input array that contains the value specified. n is the size of the array. If no element of the array contains the value, then the function should return -1. The program takes an int array, the number of elements in the array, and the value that it searches for. The main function takes input, calls the search()function, and displays the output. Name program part1.c

int search(int a[], int n, int value);

Example 1:

Enter length of array: 4

Enter elements of array: 8 2 3 9

Enter the value for searching: 2

Output: 1

Example 2:

Enter the length of the array: 6

Enter the elements of the array: 4 6 1 0 2 9

Enter the value for searching: 5

Output: -1

2. Modify the part 1 program so that it deletes all instances of the value from the array. As part of the solution, write and call the function delete() with the following prototype. n is the size of the array. The function returns the new size of the array after deletion (The array after deletion will be the same size as before but the actual elements are the elements from index 0 to new_size-1). In writing function delete(), you may include calls to function search(). The main function takes input, calls the delete()function, and displays the output. Name your program part2.c.

int delete(int a[], int n, int value);

Example 1:

Enter the length of the array: 6

Enter the elements of the array: 4 3 1 0 3 9

Enter the value for deleting: 3

Output array:

4 1 0 9

There are several typical cube computation methods such as Multi-Way, BUC, and Star-cubing. Briefly describe each one of these methods outlining the key points.

Please read the whole question and instrucions.

The instructor wants a function to convert string to int to perform the bitwise operations then convert int to string back again to show results.

Question:Write a program that produces the bitwise OR, bitwise AND, and bitwise XOR of the bit strings
1001 0011 1011 and 1111 1010 0000.

Thank you in advance.

C++ Zybook LAB15.3.1: What order? (function templates

Define two generic functions called GetVector() and CheckOrder(). GetVector() takes a string of items delimited by spaces and an item of a generic type (i.e., char, int, double, or string) and returns a vector of the given item type. CheckOrder() checks if the vector of items is in ascending, neither, or descending order. The function should return 'a' if the items are in ascending order, 'u' if the items are unordered, and 'd' if the items are in descending order.

To test your functions, you are provided a main program which: Reads items from the input one line at a time, Uses a function called DataType() to determine the type of data (e.g., char, int, etc.) in the line, Constructs a vector of the appropriate type using your GetVector() function, and Then calls your CheckOrder() to output how the items are ordered. The items can be different types, including integers, strings, characters, or doubles.

Ex. If the input is: bat hat mat sat 63.2 196.5 123.5 the output is: Order: a Order: u

Code:

#include <string>
#include <sstream>
#include <iostream>
#include <vector>

using namespace std;

// TODO: Define a generic function called GetVector() that
// takes a string of items delimited by spaces and
// an item of a generic type (i.e., char, int, double,
// or string) and returns a vector of the given item
// type. The GetVector() function signature is below.
template <typename T>
vector<T> GetVector(string items, T item);

// TODO: Define a generic function called CheckOrder() that
// takes a vector of either char, double, int or string
// type as an argument and returns 'a' if the contents
// of the vector is ascending, 'd' if descending and 'u'
// if it is neither. A vector of zero or one items is
// considered 'u'. The CheckOrder() signature is below.
template <typename T>
char CheckOrder(vector<T> v);

char DataType(string items);

int main(int argc, char* argv[]) {
// Read in items
string items, str_item = "";
char char_item = ' ';
int int_item = 0;
double double_item = 0.0;;
vector<string> sv;
vector<int> iv;
vector<double> dv;
vector<char> cv;

getline(cin, items);
while (!cin.eof()) {
// check for the type of data: DataType returns 'c' for char,
// 'd' for double, 'i' for int, and 's' for string
char type = DataType(items);

// populate the vector
switch (type) {
case 'c': cv = GetVector(items, char_item);
cout << "Order: " << CheckOrder(cv) << endl;
break;
case 'd': dv = GetVector(items, double_item);
cout << "Order: " << CheckOrder(dv) << endl;
break;
case 'i': iv = GetVector(items, int_item);
cout << "Order: " << CheckOrder(iv) << endl;
break;
default : sv = GetVector(items, str_item);
cout << "Order: " << CheckOrder(sv) << endl;
break;
}
getline(cin, items);
}

return 0;
}

char DataType(string items) {
bool chars = true;
bool strings = true;
bool ints = true;
bool doubles = true;

for (auto c : items) {
if (isalpha(c)) { ints = false; doubles = false; }
if (c == '.') { ints = false; }
}

if (ints) { return 'i'; }
if (doubles) { return 'd'; }

stringstream ss(items);
string s;

while (ss >> s) {

}

if (chars) { return 'c'; }
