Question

Write two nested for loops to calculate the following double summation: ex: if s is 3 and t is 2, then summation result is 18. (1 x 1) (1 x 2) (2 x 1) (2 x 2) (3 x 1) (3 x 2) = 18?

Answer 1

To calculate the double summation, you can use two nested for loops to iterate through the values of s and t. Inside the loops, multiply the current values of the loop variables and sum them to get the final result. For example, if s is 3 and t is 2, the result will be 18.

Step-by-step explanation:

To calculate the double summation described, we can use two nested for loops. The outer loop will iterate from 1 to s, and the inner loop will iterate from 1 to t. Inside the loops, we'll multiply the current values of the loop variables to calculate the product and sum it to a running total.

Here's an example of the code:

int s = 3;
int t = 2;
int result = 0;

for (int i = 1; i <= s; i++) {
for (int j = 1; j <= t; j++) {
int product = i * j;
result += product;
}
}

In this case, the result will be 18.
