#include <iostream>
#include<cmath>
using namespace std;


template <class T>
T SquareRoot(T a) {
T result;
result=int(a);
if(result!=a)
return -1;
else
result = sqrt(a);
return result;
}

int main () {
   /*
   we have make the "n" float type so that we can check that it is int or not as if we declare it as int then if we enter any float
   or double value then the int type variable will automatically convert it to int and due to which we can't check that whether it is int or
   any other datatype.

Write a method sumTo that accepts an integer parameter n and returns the sum of the first n reciprocals. In other words: sumTo(n) returns: 1 + 1/2 + 1/3 + 1/4 + ... + 1/n For example, the call of sumTo(2) should return 1.5. The method should return 0.0 if passed the value 0 and should print an error message and return -1 if passed a value less than 0. Include a loop. Please help for Java programming.

Python: Write a function named calc_odd_sum that accepts a positive integer as the argument and returns the sum of all the odd numbers that are less than or equal to the input number. The function should return 0 if the number is not positive. For example, if 15 is passed as argument to the function, the function should return the result of 1+3+5+7+9+11+13+15. If -10 is passes, it shall return 0. You shall run the program test the result at...

In java Write a static method named consecutiveDigits that accepts an integer n as a parameter and that returns the highest number of consecutive digits in a row from n that have the same value. For example, the number 3777785 has four consecutive occurrences of the number 7 in a row, so the call consecutiveDigits(3777785) should return 4. For many numbers the answer will be 1 because they don't have any adjacent digits that match. Below are sample calls on...

Write a C function called weighted_digit_sum that takes a single integer as input, and returns a weighted sum of that numbers digits. The last digit of the number (the ones digit) has a weight of 1, so should be added to the sum "as is". The second from last digit (the tens digit) has a weight of 2, and so should be multiplied by 2 then added to the sum. The third from last digit should be multiplied by 1...

Problem: Write a C/C++ program to implement a function that returns 1 when an integer x contains an odd number of 1s (in its binary representation) and 0 otherwise. You can consider x as a four byte integer, i.e. w = 32 bits. Constraint: Your solution can use at most 12 arithmetic, bitwise, and logical operations.
