Scan Memory for Three Consecutive Increasing Values

Code

#include <stdio.h>

int find_pattern(int *mem, int n) {
    // Write your pointer-based logic here
    for(int i=0;i<n-3;i++){
        int flag = 1;
        for(int j=i;j<i+2;j++){
            if((*(mem+j)+1) != *(mem+j+1)){
                flag = 0;
                break;
            }
        }
        if(flag) return 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;
}
