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

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。
It can be shownwith5orless moves that itisimpossibleforthearraytohaveallunique values. Note: 0 <= A.length <= 40000 0 <= A[i] < 40000 这道题给了一个数组,说是每次可以将其中一个数字增加1,问最少增加多少次可以使得数组中没有重复数字。给的两个例子可以帮助我们很好的理解题意,这里主要参考...

The first overload is used for single objects, the second overload is invoked for arrays, and the third overload prevents the prevents you from specifying an array size in the type argument (make_unique<T[N]>); this construction is not supported by the current standard. When you usemake...
