Scan Memory for Three Consecutive Increasing Values

Code

#include <stdio.h>

int find_pattern(int *mem, int n) {
    // Write your pointer-based logic here
    bool flag = false;
    for(int i=0; i<n; i++) {
        int tmp = *(mem+i);
        int cnt = 0;
        for(int j=i+1; j<=i+2; j++) {
            if((tmp+1) == *(mem+j)) {
                tmp = *(mem+j);
                cnt++;
            } else {
                break;
            } 
        }
        if(cnt == 2) 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;
}
