Scan Memory for Three Consecutive Increasing Values

Code

#include <stdio.h>

int find_pattern(int *mem, int n) {
    // Write your pointer-based logic here
    if (n < 3) return -1;

    int *p = mem;
    for (int i = 0; i <= n - 3; i++, p++) {
        // Check if *p, *(p + 1), *(p + 2) are consecutive increasing
        if (*(p + 1) == *p + 1 && *(p + 2) == *p + 2) {
            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;
}
