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