Would your school or place of work benefit from cloud computing? Identify at least two cloud computing vendors and research their features and costs. Then, examine one element of your chosen network’s infrastructure and apply it to cloud computing. Would it be feasible to migrate to the cloud? Would it be cost effective? Why or why not?

Write a program that reads a string from the user, and creates another string with the letters from in reversed order. You should do this using string concatenation and loops. Do not use any method from Java that does the work for you. The reverse string must be built. Do not just print the letters in reversed order. Instead, concatenate them in a string.

--- Sample run:
This program will create a string with letters in reversed order.
Enter a string: banana
The reversed string is: ananab
Bye

--- Sample run:
This program will create a string with letters in reversed order.
Enter a string: what the heck
The reversed string is: kceh eht tahw
Bye

Consider the following simple script incorporating a for loop:

#!/bin/bash
RED='\033[0;31m'
NC='\033[0m'
clear; cd /home
for DIR in $HOME; do
#for DIR in *;do
CHK=$(grep -c "/home/$DIR" /etc/passwd)
if [ $CHK -ge 1 ]
then
echo -e "${NC}$DIR is good"
else
echo -e "${RED}ALERT! $DIR is NOT good!"
fi
done

What kind of script is presented above? How did you make your determination? What is the purpose of the script?

In lines #5/6, what is the type of $DIR?

In line #7, what is the value of $CHK?

In line #8, what are the instructions contained with the brackets known as?

Why are there two lines containing the word "for"? Which line will execute? Will that line execute correctly?

What should you do before running the script?

How could the script be factored into your duties as a sysadmin?

Search for an element in a 2D sorted matrix using the binary search technique. Your code should run in O(m + n) where m is the number of rows and n is the number of columns
The python file should have a function named binarysearch

The function should take two arguments. The first argument of the function will be the element to search for. Second argument of the function will be the matrix as a List[List].
The function should return the row and column of the matrix if the element is found. Use a tuple to return the row and column. Return "Not Found" if the element is not found.

Sample values for input and output :

Sample Input:
Case 1: binarysearch(4, [[1, 2, 3],[4, 5, 6],[7, 8, 9]] )
Case 2: binarysearch(10,[[2, 3, 4],[5, 7, 9],[11, 12, 13],[20, 22, 24]]

Sample Output :
Case 1: (1 , 0)
Case 2: Not Found
