The module naming rules are similar to how we name packages (dots are allowed, dashes are not). It's very common to do either project-style (my.module) or Reverse-DNS (com.baeldung.mymodule) style names. 模块的命名规则类似于我们命名包的方式(允许使用点,不允许使用破折号)。 比如: ...
Write a function that takes a string as input and reverse only the vowels of a string. Example 1: Givens = "hello", return "holle". Example 2: Givens = "leetcode", return "leotcede". Note 第一种解法:将字符串转化为字符数组,用一头一尾两个指针向中间夹逼,遇到两个元音字母就进行位置交换...
