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