Scan Memory for Three Consecutive Increasing Values

Code

#include <stdio.h>

int find_pattern(int *mem, int n) {
    for (int i=0;i<n;i++){
        if (((*mem)+1)==*(mem + 1)&&(*(mem + 1)+1)==*(mem+2)){
            return i;
        }

    mem ++;
    } 
    return -1;
    
}

int main() {
    int n, arr[100];
    scanf("%d", &n);

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

    int res = find_pattern(arr, n);
    printf("%d", res);

    return 0;
}
