Reverse an Array In-Place

Code

#include <stdio.h>

void reverse_array(int arr[], int n) {
    // Your logic here
    int start_idx = 0, end_idx = n-1;

    while(start_idx < end_idx){

        int temp = 0;
        temp = arr[start_idx];
        arr[start_idx] = arr[end_idx];
        arr[end_idx] = temp;

        start_idx++;
        end_idx--;
    }

}

int main() {
    int n;
    scanf("%d", &n);

    int arr[100];
    for (int i = 0; i < n; i++) {
        scanf("%d", &arr[i]);
    }

    reverse_array(arr, n);

    for (int i = 0; i < n; i++) {
        printf("%d", arr[i]);
        if(i < n-1){
        	printf(" ");
        }
    }
    return 0;
}
