出现这个错误通常是因为尝试对不是数组的对象进行 `makeUniqueArray` 操作。确保你的变量确实是一个数组类型。你可以使用 `isArray()` 函数来检查变量是否为数组类型。解决方案 解决方案一：检查变量类型 使用 `isArray()` 函数来检查变量是否为数组类型。if (!Array.isArray(myVar)) { myVar = [my...
Given an array of integers A, amoveconsists of choosing anyA[i], and incrementing it by1. Return the least number of moves to make every value inAunique. Example 1: Input: [1,2,2]Output: 1Explanation: After 1 move, the array could be [1, 2, 3]. Example 2: Input: [3,2,1,...
Explanation: After 1 move, the array could be [1, 2, 3]. Example 2: Input: [3,2,1,2,1,7] Output: 6 Explanation: After 6 moves, the array could be [3, 4, 1, 2, 5, 7]. It can be shown with 5 orlessmoves that it is impossibleforthe array to have all unique values. ...
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...
