Reverse an Array In-Place

Code

#include <stdio.h>

void reverse_array(int arr[], int n) {
    if (arr == NULL || n<=1){
    return;
    }
    // Your logic here

int left=0;
int right=n-1;
while (left<right){
    int temp=arr[left];
    arr[left]=arr[right];
    arr[right]=temp;
    left++;
    right--;


}
}


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;
}
