499 - What's The Frequency, Kenneth?

[Darko]

You declare count[51] but you need 52?

damn thats silly...

neway thanx for the help....

Your code will still get WA even if the mistake pointed out by Darko is corrected.

Try this input:

Code: Select all

When riding your bicycle backwards down a one-way street, if the
wheel falls of a canoe, how many ball bearings does it take to fill
up a water buffalo?
Hello Howard.
Testing

Correct Output is:

Code: Select all

e 6
al 7
a 3
Hlo 2
Teginst 1

But your code prints:

Code: Select all

e 6
al 7
a 3
Hlo 2

[=viki=]

i thought the period denotes the end of input....
thats why after Hellow Howard. the program ends..

how should i know when the input ends..

[chunyi81]

Hint: use gets instead of getchar.

[=viki=]

thanx.... i got AC now.

used if(ch==EOF) instead of if(ch=='.')
to break out of loop.

Try the I/O set. Your code returns wrong...

Input:

Code: Select all

HHHHHh             ................hhhhooooOOO

Output:

Code: Select all

Hh 5

Hope it helps.

Try the following I/O set...

Input:

Code: Select all

bbbAABB.BaaaA
abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ
zzZZyyAAbb

Output:

Code: Select all

ABab 3
ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz 1
AZbyz 2

Your code returns wrong answer for the third case. Hope it helps.

[dust_cover]

hey sunny thanx a lot. actually i made a mistake of flag initialization. thanx a lot i got AC!

[sklitzz]

Hi,

I'm not sure anymore whether I have to print ABC...XYZabc...xyz 0 or a blank line or just skip that one.

Does the above work for blank lines nad those without any characters.
It's a simple task but I'm going crazy tryin figure it out.

Code: Select all

#include <iostream>
#include <string>
#include <algorithm>
#include <cstdio>
using namespace std;

#define pb(x) push_back(x)
#define mp(x,y) make_pair(x,y)
#define SQ(x) (x)*(x)

string solve( string s ) {
 	int cnt[52]; memset( cnt, 0, sizeof( cnt ) );
	for( int i = 0; i < s.size(); ++i ) {
		if( s[i] >= 'a' && s[i] <= 'z' ) cnt[ s[i] - 'a' + 26 ]++;
		if( s[i] >= 'A' && s[i] <= 'Z' ) cnt[ s[i] - 'A' ]++;
	}
	
	int x = *(max_element( cnt, cnt + 52 ) );
		
	string ret = "";
	for( int i = 0; i < 26; ++i ) if( cnt[i] == x ) ret += (i + 'A');
	for( int i = 26; i < 52; ++i ) if( cnt[i] == x ) ret += (i + 'a' - 26);
	
	ret += " "; ret += ( x + '0' );
	
	return ret;	
}

int main() {
	string s;
	while( getline( cin, s ) )
		cout << solve( s ) << endl;
		
	return 0;
}
