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 *first=mem;

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