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…

此题主要是讲给你一组数,如何将数连在一起能得到最大值(最小值反之),注意局部最优,就是说如果 123 234两个连在一起怎么样最大,显然是234123比123234大,对于3个数我们可以找到类似的性质,4个数一样...因此我们得到这个局部最优的排序是全局最优的.因此这个实现最核心的代码就是函数cmp,其他的就是要注意全是0的情况和前导0的情况,这题就轻松解决. inline bool cmp(const std::string &a, const std::string &b) { ret…
