1、Vector// 1. Vector 可变数组 // 通过构造函数创建 let v: Vec<i32> = Vec::new(); // 通过宏创建,可以推断出类型 let v = vec![1, 2, 3]; // 更新Vector let mut v = Vec::new(); // 必须是不可变,否则报错 v.push(5); v.push(6); v.push(7); v.
给你两个按非递减顺序排列的整数数组nums1和nums2,另有两个整数m和n,分别表示nums1和nums2中的元素数目。 请你 合并nums2到nums1中,使合并后的数组同样按非递减顺序排列。 注意:最终,合并后数组不应由函数返回,而是存储在数组nums1中。为了应对这种情况,nums1的初始长度为m + n,其中前m个元素表示应合并的...

Using theiter_mut()method on a collection will mutably borrow each element of the collection in each iteration. It means we can modify the collection in place. For example, fnmain() {letmutcolors =vec!["Red","Yellow","Green"];
