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 *p1= mem;
    int *p2= mem+1;
    int *p3= mem+2;

    for(int i=0; i<n;i++){
    if(*p1+1 ==*p2 && *p2+1 ==*p3){
    return i;
    }
     p1++;
     p2++;
     p3++;
    } 
    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;
}
