Given an array of 4 digits, return the largest 24 hour time that can be made. The smallest 24 hour time is 00:00, and the largest is 23:59. Starting from 00:00, a time is larger if more time has elapsed since midnight. Return the answer as a string…
[抄题]: Given a non-negative integer N, find the largest number that is less than or equal to N with monotone increasing digits. (Recall that an integer has monotone increasing digits if and only if each pair of adjacent digits x and ysatisfy x <= y.)…
一.random模块的使用: Python中的random模块用于生成随机数.下面介绍一下random模块中最常用的几个函数. 1.常用函数: (1)random.random() 用于生成一个0到1的随机符点数: 0 <= n < 1.0 (2)random.uniform(a,b) 用于生成一个指定范围内的随机符点数,两个参数其中一个是上限,一个是下限.如果a > b,则生成的随机数n: b <= n <= a.如果 a <b, 则 a <= n <=…
Given a digit string, return all possible letter combinations that the number could represent. A mapping of digit to letters (just like on the telephone buttons) is given below. Input: Digit string "23" Output: ["ad", "ae", &…
