2376. 统计特殊整数 - 如果一个正整数每一个数位都是 互不相同 的,我们称它是 特殊整数 。 给你一个 正 整数 n ,请你返回区间 [1, n] 之间特殊整数的数目。 示例 1: 输入:n = 20 输出:19 解释:1 到 20 之间所有整数除了 11 以外都是特殊整数。所以总共有 19 个
Can you solve this real interview question? Count Number of Nice Subarrays - Given an array of integers nums and an integer k. A continuous subarray is called nice if there are k odd numbers on it. Return the number of nice sub-arrays. Example 1:
You are given two strings s1 and s2 and two integers n1 and n2. You have the two strings str1 = [s1, n1] and str2 = [s2, n2]. Return the maximum integer m such that str = [str2, m] can be obtained from str1. Example 1: Input: s1 = "acb", n1 = 4, s2 = "ab", ...
