function reverseString(str) { /*首先将字符串拆分成数组;然后将该数组进行翻转,最后将数组合并为新的字符串*/ return str.split('').reverse().join(''); } 1. 2. 3. 4. 5. 二、 JS 阶乘算法 要求:计算所提供整数的阶乘。factorialize(10)应该返回 3628800. 我们可以直接使用递归的方法实现阶乘运算。
You need to reduce multiple spaces between two words to a single space in the reversed string. 题意:给定一个句子,反转句子的单词,首尾空格剔除,单词间空格保持一个空格 代码如下: /** * @param {string} s * @return {string}*/varreverseWords =function(s) {//通过空格切割字符串let sarr=s.spl...
} if(k >1) reverseSubWord( s, 0,k-1) ; } void reverseSubWord(string &s,int start,int end){ while(start<=end){ swap(s[start],s[end]); start++;end--; } } };
function reverse(str) { var re = /\b\w+\b/g; var matches; return function(tempStr) { return (matches = re.exec(str)) !== null ? arguments.callee(matches + ' ' + tempStr) : tempStr.replace(/\s$/,''); }(''); } var result = reverse('I am a coder'); console.log(result...
String str3 = new String(new char[]{'a','b','c'}) 1. charAt(int index) 方法。 我们知道一个字符串是由一个字符数组组成,这个方法是通过传入的索引(数组下标),返回指定索引的单个字符。 1 public char charAt(int index) { 2 //如果传入的索引大于字符串的长度或者小于0,直接抛出索引越界异常 ...

functionmyReducer(accumulator,arrayElement){// Code to do something goes here} accumulator是一个叠加值。它包含上次调用reducer函数时返回的所有内容。如果reducer函数还没有被调用,那么它包含初始值。因此,当我们传递add()作为reducer时,累加器映射到a+b的a部分,而a恰好包含前面所有项目的运行总数。对于multiply(...
