Scan Memory for Three Consecutive Increasing Values

Code

#include <stdio.h>

int find_pattern(int *mem, int n) {
    int count =0;


for (int i=0; i<n;i++)
{
    if (*(mem+i+1) == (*(mem+i)+1))
    {
        count++;
        if(count == 2)
        {
            return i-1;
            break;
        }
    }
    else
    {
    }
}
if (count != 3)
{
    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;
}
