Query the customer_number from the orders table for the customer who has placed the largest number of orders. It is guaranteed that exactly one customer will have placed more orders than any other customer. The orders table is defined as follows: | C…

Given a list of non negative integers, arrange them such that they form the largest number. For example, given [3, 30, 34, 5, 9], the largest formed number is 9534330. Note: The result may be very large, so you need to return a string instead of an i…

在做 Largest Number 这道题之前,我对 sort 方法的用法是非常自信的.我很清楚不传比较因子的排序会根据元素字典序(字符串的UNICODE码位点)来排,如果要根据大小排序,需要传入一个比较函数. 先来看这道题,给你一个数组,让你把数组元素拼接起来,求能拼得的最大的数.如果只有两个数字 a 和 b,如何拼?很明显比较 ab 和 ba 两个数的大小,所以这道题首先需要对数组做一次排序.刷刷写下如下代码: nums.sort(function(a, b) { return (b + '…

这两个题几乎是一样的,只是leetcode的题是排成最大的数,剑指的题是排成最小的 179. Largest Number a.需要将数组的数转换成字符串,然后再根据大小排序,这里使用to_string函数将整数转换成字符串,比printf的方式简洁 b.cmp函数必须用static才能使用 c.这题需要排成最大的数,cmp函数如何确定< .>符合呢?cmp中可以默认为a就是两个字符中的第一个,b是第二个,所以a+b>b+a返回true就继续保持这样的排列.如果是<,a+b就会返回…
