A Very Big Sum

  • somayaji + 7 comments

    What's the reason for using two loops and an array? I feel like that just takes too much time and too much space. Here's my take in C if anyone's interested:

    #include <stdio.h>

int main(void){
    int n;
    long sum=0;
    scanf("%d", &n);
    long value;
    //long arr[n];
    for (int i=0; i < n; i++) {
        scanf("%li", &value);
        sum += value;
    }
    printf("%li", sum);
    return 0;
}

          Try long long int in place of int if you are using c

      but if we intializing array in long type after then we are inputing it and summing it then it is showing runtime error.. can you tell me why this happening or i am wrong??

      It will only run for numbers less than 10 digit not more than that.
