Two Strings Interchange Vowels

 Two Strings Interchange Vowels 

PROBLEM STATEMENT :

The program must accept two string values S1, S2 (both having equal number of vowels) and interchange the vowels in the string values in their order of occurrence. 

Boundary Condition(s): 

1 <= Length of S1, S2 <= 1000 

Input Format: 

The first line contains S1. 

The second line contains S2. 

Output Format: 

The first line contains S1 with the vowels interchanged. 

The second line contains S2 with the vowels interchanged. 

Example Input/Output 1: 
Input: () 
apple 
rain 
Output: 
appli 
raen 

Explanation: 

Here S1 = apple and S2 = rain. 

After interchanging the vowels in the string values in their order of occurrence, the string values become 

S1 = appli and S2 = raen. 

Example Input/Output 2: 
Input: () 
PANCAKE 
Umbrella 
Output: 
PUNCeKa 
AmbrAllE

SOLUTION :

C (Programming Language)

      
#include<stdio.h>
#include<stdlib.h>
int isvowel(char w){
    char k=tolower(w);
    if(k=='a'||k=='e'||k=='i'||k=='o'||k=='u')
    return 1;
    return 0;
}
int main()
{
    char str1[1000],str2[1000],t;
    scanf("%s\n%s",str1,str2);
    int i,j,k=0;
    for(i=0;i<strlen(str1);i++){
        if(isvowel(str1[i])){
            while(isvowel(str2[k])==0){
             k++;
            }
            t=str1[i];
            str1[i]=str2[k];
            str2[k]=t;
            k++;
        }
       
    }
    printf("%s\n%s",str1,str2);
}
 

C++ (CPP)

       
#include <bits/stdc++.h>
 
using namespace std;

int main(int argc, char** argv)
{
    int i,j=-1;
    string s1,s2;
    cin>>s1>>s2;
    for(i=0;i<s1.size();++i)
    {
        if(strchr("aeiou",tolower(s1[i])))
        {
            while(!strchr("aeiou",tolower(s2[++j])));
            swap(s1[i],s2[j]);
        }
    }
    cout<<s1<<endl<<s2;
}
 

JAVA

       
import java.util.*;
public class Hello {
    public static void main(String[] args) {
		Scanner sc=new Scanner(System.in);
		String s=sc.next();
		String t=sc.next();
		String src="AEIOUaeiou";
		char ch[]=s.toCharArray();
		char ch1[]=t.toCharArray();
		int start=0;
		for(int i=0;i<ch.length;i++){
		    if(src.contains(String.valueOf(ch[i]))){
		        for(int j=start;j<ch1.length;j++){
		         if(src.contains(String.valueOf(ch1[j]))){
		           char temp=ch[i];
		           ch[i]=ch1[j];
		           ch1[j]=temp;
		           start=j+1;
		           break;
		         }
		        }
		    }
		}
		String n=String.valueOf(ch);
		String n1=String.valueOf(ch1);
		System.out.printf("%s\n%s",n,n1);
	}
}
 

PYTHON

       
s1=list(input().strip())
s2=list(input().strip())
l1=len(s1);l2=len(s2);j=0
for i in range(l1):
    if s1[i].lower() in "aeiou":
        while j<l2 and s2[j].lower() not in "aeiou":
            j+=1
        s1[i],s2[j]=s2[j],s1[i]
        j+=1
print(''.join(s1),''.join(s2),sep='\n')
