499 - What's The Frequency, Kenneth?

[sophi]

My output matches with UVA toolkit but I got WA . But can't find out what's the problem is.
Help please.

Don't double post.

[brianfry713]

Doesn't match the sample I/O.

[sophi]

I changed my while loop like that

Code: Select all

while(gets(str)!=NULL)

Now it matches the sample I/O But again WA
what's the problem now ?

[brianfry713]

Doesn't match the sample I/O. Post your complete updated code.

My Complete code is given here.My I/O matches with the I/O given by @ PromeNabid previously in this topic.

On line 24 you clear arr[52], which is not part of an array declared as int arr[52]; (valid are arr[0] through arr[51]).

On 499 don't read from a file.

[brianfry713]

On 10300 (and all problems) print a newline char at the end of the last line.
