Holes in a string

java

#1

Count the holes
if D,O,P,Q,A have 1 hole
and B has 2 hole

input word: BABOY

output:6 holes


#2

@cris18 traverse the string and do follows:

int main()
    {
    char st[100];
    scanf("%s",st);
    int l = strlen(st);
    for(int i=0; i<l; i++) {
    if(st* == 'A'||st* == 'D'||st* == 'P'||st* == 'O'||st* == 'Q')
      count += 1;
    if(st* == 'B')
       count += 2;
    }
    printf("%d Holes

",count);
return 0;
}

Happy Coding!!!

Just timepass :wink:

#include<iostream>
#include<cstdio>
#include<cstring>

using namespace std;

int holes[26] = {1, 2, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 1, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0};

int main() {
    char s[100];
    cin>>s;
    int len = strlen(s);
    int hcount = 0;
    for(int i=0; i<len; i++) {
		hcount += holes[s* - 'A'];
    }
    cout<<hcount<<endl;
    return 0;
}

Here is the Java solution you seem to need.

public static void main(String[] args) throws IOException {

    BufferedReader in = new BufferedReader( new InputStreamReader( System.in ) );
    BufferedWriter out = new BufferedWriter( new OutputStreamWriter( System.out ) ):

    String s = in.readLine(); // Accepts the word as input.

    int count = 0;
    for( int i = 0; i < s.length(); i++ ) {

        // Checks if the character has one hole. R also has a hole.
        if( s.charAt( i ) == 'D' || s.charAt( i ) == 'O' || s.charAt( i ) == 'P' || s.charAt( i ) == 'Q' || s.charAt( i ) == 'A' |} s.charAt( i ) == 'R' ))
              count++;
        // Checks if the character has two holes.
        else if ( s.charAt( i ) == 'B' )
              count += 2;

    }

    out.println( count );
    out.flush();
    out.close();
}

This solution assumes that the word given as input will be one line. If it isn’t, a slight modification to the input acceptance will have to be made. This runs O(N) time where N is the length of the word.

import java.util.*;

class Hello

{

public static void main(String args[]){

System.out.print("Enter String : ");

Scanner sc=new Scanner(System.in);

String input=sc.next();

int holes=0;

for(int i=0;i<input.length();i++)

{

char ch=input.charAt(i);

if(ch==‘D’||ch==‘O’||ch==‘P’||ch==‘Q’||ch==‘A’)

holes++;

else if(ch==‘B’)

holes=holes+2;

}

System.out.println(" Holes in string “+input+” are = "+holes);

}

}

DEMO -

Enter String : BABA

Holes in string BABA are = 6

R has no holes? :confused: R should have 1 hole as well. My code includes that.
