自定义 make_unique_array 函数: 这个函数模板接受一个数组大小和类型作为参数,并返回一个指向该类型数组的 std::unique_ptr。 使用new T[size]() 动态分配数组,并初始化为默认值(对于内置类型如 char,默认值为 0)。 在main 函数中使用 make_unique_array: 创建一个大小为 10 的字符数组。 使用循环初始化数...

945. Minimum Increment to Make Array Unique (使数组唯一的最小增量) 链接 https://leetcode-cn.com/problems/minimum-increment-to-make-array-unique 题目 给定整数数组 A,每次 move 操作将会选择任意 A[i],并将其递增 1。 返回使 A 中的每个值都是唯一的最少操作次数。 示例1: 输入:[1,2,2] 输出...
[Tips + Javascript] Make a unique array To make an array uniqued, we can use Set() from Javascript. const ary = ["a", "b", "c", "a", "d", "c"]; console.log(newSet(ary)); We can see that all the duplicated value have been removed, now the only thing we need to do ...
