Write a Modular C Programming code to solve Sum except for that element, Find the sum of all elements of an array except that element at index i
Find the sum of all elements of an array except that element at index i, and store the answer in a new array.
Example:
arr[]={10,20,30,40,50};
output_array={140,130,120,110,100}
Explanation: Sum of all elements except at index 0 is 140 (20+30+40+50), therefore store 140 at index 0.
Sum of all elements except at index 1 is 130 (10+30+40+50), therefore store 130 at index 1.
Sum of all elements except at index 2 is 120 (10+20+40+50), therefore store 140 at index 2.
Sum of all elements except at index 3 is 110 (10+20+30+50), therefore store 140 at index 3.
Sum of all elements except at index 4 is 100 (10+20+30+40), therefore store 140 at index 4.
Input Format
First-line contains a number of test cases. the second line contains N, the number of array elements the Third line contains N array elements separated by space
Constraints
1<=N<=10^5
Output Format
Output the new array for each test case in a new line.
Sample Input 0
