Is Palindrome

Discussions Toph Problems

Here is why may that happen:

On Windows, line endings are represented with two characters: “\r\n”. “\r” is called carriage return, and “\n” is called line feed. Whenever you are pressing the enter key, you are essentially adding these two characters to the buffer.

On most non-Windows platforms, line endings are represented with just “\n”.

When you use fgets() to read the input, it is actually making “\r” a part of the string.

This is why it is a smarter idea to use scanf("%s", ...) to read strings in C whenever possible. And use fgets when you absolutely need to. You could try it out on Windows and see if that helps.

I used scanf(“%s”,) and this was the final solution. Sorry for disturbing you, and thanks a lot for helping me.

This was not disturbing. :slight_smile:

I often ask help from the good programmer guys and all of them get disturbed. Anyway thanks.

printf(“Yes”);
break;
}
else
{
continue;
}
}
else
{
printf(“No”);
break;

use this instead of-
printf(“yes”);
break;
}
else
{
continue;
}
}
else
{
printf(“no”);
break;

please remove accepted codes from everywher. You have already done it couple of times. I might report you next.

sorry bro
I didnt know it works
how I can remove them?
I’ll definitely do this now. sorry again

#include <stdio.h>
#include <string.h>
int main() {
	char p[100];
	scanf ("%c",&p);
	int x=strlen(p);
	int a,b=x-1;
	for (a=0; a<=b; a++,b--){
		if (p[a]==p[b]){
			continue;
			
			
		}
		else if (p[a]!=p[b]){
			break;
		}
	}
	if (a==b+1 || a==b+2){
		printf ("Yes");
	}
	else {
		printf ("No");
	}
	
	return 0;
}

Where is the fault?

31 
#include<stdio.h>
#include<string.h>
int main()
{
    char s[101];
    scanf("%s",&s);
    int len=strlen(s),i,j=0;
    for(i=0;i<=(len-1)/2;i++)
    {
        if(s[i]!=s[len-1-i])
        j=1;
        break;
    }
    if(j!=1)
    {
        printf("Yes");
    }
    else printf("No");
    
}

whats wrong here?

32

#include
#include <string.h>

using namespace std;

int main()
{
char a[100],b[100];
cin>>a;
strcpy(b,a);
strrev(b);
if(strcmp(a,b)==0)
cout<<“Yes”;
else
cout<<“NO”;

return 0;

}

code is ok but why not accept.

33 
#include <stdio.h>
#include<string.h>
int main() {
	char s[100];
	
	 scanf("%s",s);
	int i,g,k;
    k=strlen(s);
		for(g=k-1,i=0;g>=0,i<=k-1;g--,i++){
			if (s[i]==s[g]){
printf("Yes");
				break ;
				}
else{
	printf("No");
	break;
}
		}
	
	
	
	return 0;
}

what s wrong here??

34

What is the error?

#include<stdio.h>
int main()
{
    char str1[100],str2[100];
    int count=0,i,j=0;
    printf("\n");
    scanf("%[^\n]",str1);
    
    
    for(i=0;str1[i]!='\0';i++)
        count+=1;
        
    for(i=count-1;i!=-1;i--)
        str2[j++]=str1[i];
        
    str2[j]='\0';
    
    if(str1==str2)
    {
        printf("Yes");
    }
    else
    {
        printf("No");
    }
    return 0;
}

S = input()
if len(S) % 2 == 0:
for i in range(len(S)):
if S[i-1] == S[-1]:
return Yes

else:
return No

what is my mistake(pls helpsomeone)

36

in python:
S = input().lower()

w = “”
for i in S:
w = i + w

if (S == w):
print(“Yes”)
else:
print(“No”)

Welcome to Toph Community @wahidpro,

Looks like you have already solved the problem. Good work!

Looks like you have solved your problem. It could have been because of using the wrong class name and package declaration.
