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 conceq_len_count =0;
    for (int needle_pos = 0; needle_pos < n; needle_pos++)
    {
        if( ((*(mem + needle_pos + 1)) - (*(mem + needle_pos))) == 1)
        {
            conceq_len_count++;
            if (conceq_len_count == 2)
            {
                return (needle_pos - 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;
}
