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 cnt = 0;
    for(int i = 0; i < n-2; i++)
    {
        for(int j = i ; j < 2; j++)
        {
            if((*(mem+j) +1) == *(mem+j+1))
            {
                cnt++;
            }
            else 
            {
                cnt = 0;
            }
        }
        if(cnt == 2)
        {
            return i;
            //break;
        }
    }
    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;
}
