Scan Memory for Three Consecutive Increasing Values

Code

#include <stdio.h>

int find_pattern(int *mem, int n) {
    // Write your pointer-based logic here
    int hit = 0;
    for (int i = 0; i < n - 1; i++) {
        if (*(mem + i) == *(mem + i + 1) - 1) {
            hit++;
        } else {
            hit = 0;
        }

        if (hit == 2) return i - 1;
    }
    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;
}
