[newton]

thank you verymuch mr Jan.
first time the same code was Wrong to UVA



keep helping

[Jan]

Your code looks correct to me. Try submitting it again.

[Jan]

Remove ansi_prime[]. And use scanf("%s") to take the input.

[fR0D]

Plz help me.First time i m trying to submit a code in Java and it gives RTE.I have done all my previous submissions in C++.

Code: Select all

GOT AC

I submitted the same code using C++ and i got accepted.I just changed only the usual input/output and string functions.

[usuario]

Hi, I got AC, your input is right.

Input:

ddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddd

Hello brothers,i m getting WA for 10789,my code gives correct output for every input in the board,can u hlp me whats the wrong??advanced thank to the helpers

got ac....

[Jan]

Check the line..

Code: Select all

...
for(j=0;j<25;j++)
...

Change it to

Code: Select all

...
for(j=0;j<26;j++) // because 26 characters are there, your code will not print z otherwise
...

Hope it helps. (Don't forget to change both the loops)
