Find Maximum Element Using Pointer Walk

Code

#include <stdio.h>

#define INT_MIN -256

int find_max_element(int *ptr, int n) {
    int max =INT_MIN;
    
    while(n>0){
        max= max ^ ((max ^ *ptr) & -(max<*ptr));
        n--;
        ptr++;
    }
    return max;
}

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

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

    int result = find_max_element(arr, n);
    printf("%d", result);

    return 0;
}
