What should be done when your sample input output matches but still I get WA ?

Thanks for the suggestion though knew it already. It is obvious that if a funciton is overloaded for some types and I am passing a value of other type, then I should type cast. But, I did not ask what I should do when I get this message.

I see that math functions of judge's compiler are overloaded ...

Well, not only a bit politeness, but also I know the degree of politeness. The way you said -
"If so, then everything is ok and that's the only message you should get. I already wrote why a month or two ago - search and you will find."
-&-
"You haven't read what you're replying to?"
was polite to a ...

Any one help me know why this code gets WA...

[cpp]#include <cstdio>
#include <cstring>

int lastDigitOfMPowN( int m, int n )
{
int ld;
int nmod4;

nmod4 = n % 4;

switch ( m ) {

case 0:

ld = 0;

break;
case 1:
ld = 1;
break;
case 2:

if ( n == 0 ) {
ld = 1;
} else {
switch ( nmod4 ...

I read that, but it is confusion that whether Duleba a single person or two. That posting contains a compiler error message,

"t.cpp:7: call of overloaded `acos(int)' is ambiguous
/usr/include/math.h:51: candidates are: double acos(double)
/usr/include/c++/3.2/cmath:112: long double std::acos ...

In " The Input " section of 10013 - " Each of the two given integers is not less than 1, and the length of their sum does not exceed M ." <-- what does it really mean?
I could get ac long ago if I did not read this line. then this line is surely misleading one.
Problems may be misleading, but ...

I got similar CE at past. OJ gives details of compilers error messages; I checked and found that their compiler found amguity while passing the value to abs( ) or log( ), as these are overloaded for several data types except the one I passed. I can't remember, exactly what was written there.

And ...

I see that math functions of judge's compiler are overloaded ( when I use <cmath> ). Should they be ? As C math functions are inherited as they were, they should not have been overloaded as they were not. I do not also see any specification by TC++PL stroustrup. Then why are they overloaded ?
