String input = "This is a sentence in English";
String[] inputSplit = input.split("a");
input = inputSplit[0];
for(int i=1; i<inputSplit.length-1; i++) {
   input += "the"+inputSplit[i];
}

OR

String input = "This is a sentence in English Language";
input.replaceAll("a","the");

Oh, I thought, It was asked to replace occurance of "a" with "the". But, the logic seems correct!

Class Prob
{
String Actual="A man walks in with the Bat";
String converted="";
StringTokenizer st= new StringTokenizer(Actual);


if(st.hasMoreTokens())
{
if(st.nextToken.equals("a")
	Converted= Converted + "the";
else
	Converted= Converted + st.nextToken;
}
System.out.Println(Converted);

}

Am a fresher.. Do correct me if I am wrong


char str= "this is a test string";
for(i=0;i<strlen(str);i++)
{
if(str[i]=='a' && str[i+1]==' ' && str[i-1]==' ')
{
replace(str, 'a', "the");
}
printf("%c", str);

#include<stdio.h>
#include<string.h>

int main()
{
int i,k;
char buf1[100];
char buf2[]="aaaaaaaaa";
int j=strlen(buf2);
printf("The length of the string is %d\n",j);
k=0;
for(i=0;i<j;i++)
{

if(buf2[i]=='a')
{
buf1[k++]='t';
buf1[k++]='h';
buf1[k++]='e';
}
else
buf1[k++]=buf2[i];

}

k=0;
while(buf1[k]!='\0')
{
printf("%c",buf1[k]);
k++;
}

}


I am a Finance major and was called for S/W dev.becoz I have an undergrad in CS. I am sure I cannot write code like you guys but I am just sharing my code too

Here is the same man again... Reliability 101%

#include<stdio.h>
#include<conio.h>
#include<string.h>
#define MAX 100

void replace(char[],int);
int main()
{
    char str[MAX]="Brendon Mccullum smashes a ball a long way!";
    int i=0;
    int flag=0;
    printf("\nEnter a string: ");
    gets(str);
    printf("\n%s",str);

    
    while(str[i]!='\0')
    {
          flag=0;
          if(str[i]=='a')
          {
                         if((str[i-1]==' ' && str[i+1]==' ') || (str[i-1]==' ' && str[i+1]=='\0'))
                             flag=1;
          }
          if(flag==1)
          {
                     //printf("\nThe value of i should be 9. It is %d", i);
                     replace(str,i);
          }
          i++;
    }
   
    getch();
    printf("\n%s",str);
    getch();
    return 0;
    
}

void replace(char a[],int pos)
{
     int i=1,j=0,k=0,l=1;
     //printf("\n%c",a[pos+2]);
     j=strlen(a)-1;
     //printf("\n%d",j);
     a[j+3]='\0';
     k=j-pos;
     for(i=j,l=1;l<=k;i--,l++)
     {
          //printf("\nIt does work fine till here");
          a[i+2]=a[i];
          //printf("\nHere??? %d",i);
          //getch();
     }
     a[i]='t';
     a[i+1]='h';
     a[i+2]='e';
}

//Making a new string << not changing the actual one >>
//Pesudo code for going in O(n) time and O(n) memory
1. Count No. of single 'a' in the string in O(n).
2. Allocate newstring = strlen(string)+3*num_of_a memory
3. Now scan the string from left and on coming of a put the and continue till end

Solution in python:

'''Replace all single occurrences of "a" with "the" (See question posted by Troy on Oct 7 2010)'''
def replace(str):
    
    i = 0
    res = ""
    for s in str:
        
        try:
            test_condition = str[i-1] == ' ' and str[i+1] == ' ' and s == 'a'
        except IndexError:
            pass    # ignore index out of range.
        
        if test_condition:
            res = res + 'the'
        else:
            res = res + s
            
        i = i+1
        
    return res
    
string = "This is not a town we were looking for; this is an apple orchard"
print replace(string)
# output: This is not the town we were looking for; this is an apple orchard

''' regex solution. achieves the same thing.'''
import re
re.sub(r'\ba\b', 'the', string)

Hmm.. seems like some of you guys did not even run your code to check its correctness..

class Main
{
    public static void main(String[] args) throws java.lang.Exception {
        String input = "This is not a town we were looking for; this is an apple orchard";
        String result = "";
        java.util.StringTokenizer st = new java.util.StringTokenizer(input);
        
        while (st.hasMoreTokens()){
            String curr = st.nextToken();
            if (curr.equals("a") ) {
                result += "the";
            } else {
                result += curr;
            }
            if (st.hasMoreTokens()){
                result += " ";
            }
        }
        System.out.println(result);
    }
