Scan Memory for Three Consecutive Increasing Values

Code

#include <stdio.h>

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