What is the meaning of testcase here

#1

Can you explain what is the meaning of testcase here. When it is asked in the question that user will enter number of testcases, what does it mean

#2

@rg361 Testcases here means that in an single input file you will be given ‘t’ no. of different arrays and for each array you have to print the answer. So for example : Input file will be like :
2
7
8 -8 9 -9 10 -11 12
4
1 2 3 4
So here two different arrays are given and you have to print there answers in separate lines.
output =
22
10
To implement this in code You just have to make a for loop which will iterate ‘t’ times.

for(int i = 0; i < t; i++){
//Take input array and do the function here.
}
