Question

Define a function named summation. This function expects two numbers, named low and high, as arguments. The function computes and returns the sum of the numbers between low and high, inclusive.

Answer 1

Answer:

public static int summation(int low, int high) {

       int sum = 0;

       for(int i=low; i<=high; i++) {

           sum += i;

       }

       return sum;

   }

Explanation:

- Initialize sum variable to hold the sum

- Inside the for loop which iterates from low to high, calculate the sum of the numbers between low and high

Then:

- Return the sum
