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 cnt=0;
    int index=0;
    int prev=0;
   // int start=0;
    while (index<n){
        if ((*mem-prev==1&&index!=0)){
            cnt++;
            
        }
        else if (*mem-prev!=1&&index!=0) { 
            cnt=0;

        }

        if (cnt==2){
            return index-2;
        
        }
        prev=*mem;
        index++;
        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;
}
