Actually, I didn't get it. I didn't use a cout to print a null character. so please can you tell me where is the bug. if you can then please tell me what should i do to not print a null character so that i can learn that error. Thanks

I didn't find the bug. Thanks in advance.

#include <algorithm>
#include <bitset>
#include <cstring>
#include <cctype>
#include <cmath>
#include <iostream>
#include <list>
#include <map>
#include <queue>
#include <string>
#include <set>
#include <stack>
#include <stdio.h>
#include <sstream ...

It is printing a space before start of each output.
