Background

Congcong is playing a number game recently, and he needs to find specific number patterns in an integer array.

Problem Description

Given an array of integers, return true if the array contains two 7's next to each other, or there are two 7's separated by one element, such as with $\{7, 1, 7\}$.

Input Format

false

Sample Explanation

Sample 1: The array contains two 7's next to each other. Sample 2: The array contains two 7's separated by one element. Sample 3: The array does not contain two 7's next to each other, nor two 7's separated by one element.

Constraints

Time limit: $1$ second, Memory limit: $1024$ KiB for each test case.
