Scan Memory for Three Consecutive Increasing Values

Code

#include <stdio.h>

int find_pattern(int *mem, int n) {
    int *start = mem;
    for (int i = 0; i <= n - 3; i++) {
        int *p = start + i;
        if (*(p + 1) == *p + 1 && *(p + 2) == *(p + 1) + 1) {
            return i;  // Return the starting index of the pattern
        }
    }
    return -1;  // No pattern found
}

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\n", res);

    return 0;
}
