今天在学习highcharts时,遇到了一个把字符串数组转换为整形数组的问题,拿在这里讨论一下: 比如有一个字符串: var dataStr="1,2,3,4,5"; 现在需要把它分割为int型数组: var dataIntArr=[1,2,3,4,5]; 怎么做?方法有很多,这里举两个有意思的: var dataStr="1,2,3,4,5";//原始字符串 var dataStrArr=dataStr.split(",");//分割成字符串数…
//import java.util.Arrays; //包含Arrays //import java.util.Random; public class HelloWorld { public static void main(String[] args){ // Scanner s = new Scanner(System.in); // System.out.println("请输入一个数字"); // int num = s.nextInt(); YanghuiSanjiao(…
Given an input string, reverse the string word by word. For example, Given s = "the sky is blue", return "blue is sky the". Update (2015-02-12): For C programmers: Try to solve it in-place in O(1) space. click to show clarification. Cl…
1.Java 1-1.字符串数组=>字符串:StringUtils: join(Object[] array, String separator) 例: Java代码 收藏代码 import org.apache.commons.lang.StringUtils; public class StringUtilsTrial { public static void main(String[] args) { // Join all Strings in the Array into a Sing…
To some string S, we will perform some replacement operations that replace groups of letters with new ones (not necessarily the same size). Each replacement operation has 3 parameters: a starting index i, a source word x and a target word y. The rul…
var dataStr="1,2,3,4,5";//原始字符串 var dataStrArr=dataStr.split(",");//分割成字符串数组 var dataIntArr=[];//保存转换后的整型字符串 //方法一 dataStrArr.forEach(function(data,index,arr){ dataIntArr.push(+data); }); console.log(dataIntArr); //方法二 dataIntArr=dataS…
