Scan Memory for Three Consecutive Increasing Values

Code

#include <stdio.h>

int find_pattern(int *mem, int n) {
    int pos = 0;
    int cnt = 0;
    for(int i=0; i<n-1; i++){
        pos++;
        if((*mem + 1) == *(mem + 1)){
            cnt++;
            if(cnt >= 2) return pos - cnt;
        }else{
            cnt = 0;
        }
        mem++;
    }
    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;
}
