Here is my c++ solution, you can watch the explanation here : https://youtu.be/b7KAvErmVIw

int simpleArraySum(vector<int> ar) {
    int sum = 0;
    for(int i = 0; i < ar.size(); i++){
        sum += ar[i];
    }
    return sum;
}

It's my solution in C++ but it's not working don't know why

int simpleArraySum(vector ar) { int ans = 0; int size = sizeof(ar) / sizeof(ar[0]); for(int i=0; i

here is my python code for the given problem

def simpleArraySum(ar):
    sum=0
    for i in ar:
        sum=sum+i
        i=i+1
    return sum

solved
