I could not get it for recursively, but iteratively, I coded a solution. If
anyone knows recursively,
let us know please.
#include<stdio.h>
void main()
{
char s[18]="DGGDBCBHH";
int i=0,j=0;
int count;
while(s[i]!='\0')
{
if(s[i] == s[i+1])
{
count = strlen(s)-2;
while(count--)
{
s[i]=s[i + 2];
i++;
}
s[i]='\0';
i=0;
}
else
{
i++;
}
}
printf("%s",s);
getch();
}
I/P: DGGDBCBHH O/P: BCB
Best Regards
Abhijit
