Scan Memory for Three Consecutive Increasing Values

Code

#include <stdio.h>

int find_pattern(int *mem, int n) {
    // Write your pointer-based logic here
    
    for (int i = 0; i < n - 2; i++)
    {
        int a = *(mem + i);
        int b = *(mem + i + 1);
        int c = *(mem + i + 2);

        if ((a + 1 == b) && (b + 1 == c)){
            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;
}
