my code does not run for the input 1 and 1000 or any other larger inputs

Question

when i am trying to run this code for input 1 and 1000 it shows me segmentation fault .what will be the correction in this code ?

void sorting(int sum[],long int         


        

Answer 1

The segmentation fault is caused by stack overflow. This line:

int sum[100000]; 

sum uses 400K spaces of stack, which is bigger than the normal size of stack.

To fix the problem, you can use std::vector to implement sum instead.
