Count pair sums that are factors of the sum of the array | Function to find the number of pairs whose sums divides the sum of array.
Initialize the totalSum and count as 0.
Calculate the total sum of array.
Generate all possible pairs.
If the sum is a factor of totalSum or not.
Increment count by 1.
Print the total count obtained.
