算法设计（在字符串中复制元音）

本文概述

C ++
Java
Python3
C#

给定字符串"str", 任务是在此字符串中复制元音。
例子：

Input: str = "geeks" Output: geeeeksInput: str = "java" Output: jaavaa

方法:使用循环迭代字符串。检查字符是否为元音，并重复它。返回并打印结果字符串。
【算法设计（在字符串中复制元音）】下面是上述方法的实现：
C ++

//C++ program for printing string //with duplicate vowels#include < bits/stdc++.h> using namespace std; //Function to check for the Vowel bool isVowel( char ch) { ch = toupper (ch); return (ch == 'A' || ch == 'E' || ch == 'I' || ch == 'O' || ch == 'U' ); }//Function to get the resultant string //with vowels duplicated string duplicateVowels(string str) { int t = str.length(); //Another string to store //the resultant string string res = "" ; //Loop to check for each character for ( int i = 0; i < t; i++) { if (isVowel(str[i])) { res += str[i]; } res += str[i]; }return res; }//Driver Code int main() { string str = "helloworld" ; //Print the original string cout < < "Original String: " < < str < < endl; string res = duplicateVowels(str); //Print the resultant string cout < < "String with Vowels duplicated: " < < res < < endl; }

Java

//Java program for printing string //with duplicate vowels import java.util.*; class GFG {//Function to check for the Vowel static boolean isVowel( char ch) { ch = Character.toUpperCase(ch); return (ch == 'A' || ch == 'E' || ch == 'I' || ch == 'O' || ch == 'U' ); }//Function to get the resultant string //with vowels duplicated static String duplicateVowels(String str) { int t = str.length(); //Another string to store //the resultant string String res = "" ; //Loop to check for each character for ( int i = 0 ; i < t; i++) { if (isVowel(str.charAt(i))) res += str.charAt(i); res += str.charAt(i); } return res; }//Driver Code public static void main(String[] args) { String str = "helloworld" ; //Print the original string System.out.println( "Original String: " + str); String res = duplicateVowels(str); //Print the resultant string System.out.println( "String with Vowels duplicated: " + res); } }//This code is contributed by //sanjeev2552
