Scan Memory for Three Consecutive Increasing Values

Code

#include <stdio.h>

int find_pattern(int *mem, int n) {
    // Write your pointer-based logic here
    for (int i  = 0; i <= n-3; i++) {
        int diff1 = *(mem+i+1) - *(mem+i);
        int diff2 = *(mem+i+2) - *(mem+i+1);
        
        if (diff1 == 1 && diff2 == 1) {
            return i;
        }
    }
    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;
}
