The time complexity of this solution isO(n), wherenis the number of digits in the integer. Adding to aHashSetand checking its size are bothO(1)operations, but we still have to iterate through each digit. 4. Using Stream API Java’sStream APIprovides a concise and modern solution to coun...

Count Consecutive Digits in Integer Count consecutive digits and say it. For example, return 132341 if input is 1112224. There are three 1s, three 2s and one 4. 反转字符法 复杂度 时间O(N) 空间 O(1) 思路 因为数字不好从前向后遍历每一位(要先统计一共有多少位,比较麻烦),所以我们直接从后...
