2023-05-11 08:02:18 来源:哔哩哔哩

Given a binary string sand a positive integer n, return trueif the binary representation of all the integers in the range [1, n]are substrings of s, or falseotherwise.

A substring is a contiguous sequence of characters within a string.

Example 1:

Input: s = "0110", n = 3

Output: true

Example 2:

Input: s = "0110", n = 4

Output: false

Constraints:

1 <= s.length <= 1000

s[i]is either '0'or '1'.

1 <= n <= 109

使用自带函数Integer.toBinaryString()就可以的,遍历确认接,下面是代码:
