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;
    for(int i = 1;i<n;i++){
       if(mem[i] == (mem[i-1]+1)) {
        count++;
       }
       else{
        count = 0;
       }

       if(count==2){
        return i-2;
       }
    }
    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;
}
