492 - Pig-Latin

[jfvs]

why do you output 10htay from the line 10th amr saqr? Im getting WA... and I think that my code is correct...

Code: Select all

import java.io.*;
import java.util.*;

public class p492 {
	static boolean is_vowel(char c){
		switch(c){
			case 'a': case 'e': case 'i': case 'o': case 'u': 
			case 'A': case 'E': case 'I': case 'O': case 'U':
				return true;
		}
		return false;
	}
	
	public static void main(String args[])throws IOException{
		Scanner e = new Scanner(System.in);
		String line;
		while(e.hasNext()){
			line = e.nextLine();
			char cline[] = line.toLowerCase().toCharArray(), 
			rline[] = line.toCharArray(), c = '\n';
			if(cline.length > 0) c = cline[0];
			boolean starts = (c >= 'a' && c <= 'z')? true : false, move = false, vowel = false;
			StringBuilder word = new StringBuilder();
			for(int i = 0; i < cline.length; i++){
				c = cline[i];
				if(!(c >= 'a' && c <= 'z')){
					String add = rline[i] + "";
					while(++i < rline.length && !((c = cline[i]) >= 'a' && c <= 'z'))
						add += rline[i] + "";
					i--;
					if(move){
						char cc = word.charAt(0);
						word = word.deleteCharAt(0);
						word.append(cc);
					}
					if(vowel) word.append("ay");
					word.append(add);
					System.out.print(word);
					word = new StringBuilder();
					starts = true; vowel = false; move = false;
				}else{
					if(starts){
						move = !is_vowel(c);
						starts = false;
					}
					vowel |= is_vowel(c);
					word.append(rline[i]);
				}
			}
			if(word.length() != 0){
				if(move){
					char cc = word.charAt(0);
					word = word.deleteCharAt(0);
					word.append(cc);
				}
				if(vowel) word.append("ay");
				System.out.print(word);
			}
			System.out.println();
		}
	}

This is very important A "word'' is defined as a consecutive sequence of letters (upper and/or lower case). This means words can be separated by anything else other than alphabets. I solved this problem using getchar() as well as using gets(). If you use gets, your array size must be very huge(or else you will get Runtime Error). At first my char array size was 10000000 but I got Runtime error. Later, I declared this array globally and increased its size to 1000000000 and got Accepted easily. However, this problem is much easier and convenient to solve if getchar() is used. So I would recommend to use:

Code: Select all

while (scanf("%c", &ch)!= EOF)

[shaon_cse_cu08]

I thing its a Clever call.... See the last word... It must be apended by a non-alphabetic character.... (space or . or something else)

Code: Select all

Input:
Amar nam shaon
Amar nam shaon.
10th
10th <--(space)
10th.
10th,
10th"

Output:
Amaray amnay haon
Amaray amnay haonsay.
10h
10htay 
10htay.
10htay,
10htay"

plz heip me ,,,, plz ... i can not try another problem b4 getting AC in 492 ,,,,,,,,,,, plz help me....

[sonjbond]

plz help .... reply my post plz....

My AC code reads the input one character at a time, not a line at a time.

Doesn't match the sample I/O.

Doesn't match the sample I/O.

I changed but RE!!

[brianfry713]

Try reading a single character at a time instead of line by line.

why i m getting RTE ??
plz help me .........
my code is here :

#include<stdio.h>
#include<ctype.h>
#include<string.h>
int isvowel(char ch)
{
if(ch=='a'||ch=='e'||ch=='i'||ch=='o'||ch=='u'||ch=='A'||ch=='E'||ch=='I'||ch=='O'||ch=='U')
return 1;
else return 0;
}
int main()
{
int i,len,j,k;
char str[1000000];
while(gets(str))
{
len=strlen(str);
for(i=0;i<len;i++)
{
if(isalpha(str))
{
if(isvowel(str)==1)
{
printf("%c",str);
i++;
while(isalpha(str))

eepbay eepBay Uuay-ppay looobay**

A couple of additional comments:

• Your code seems to assume that '.' (dot) and ' ' (space) are "special" characters to be tested for. Carefully read the problem statement again. Input could be classified as words and non-words. *Any* character that is not an uppercase or lowercase letter, is considered part of a non-word and must be left unchanged, and printed that way.
• The strlen function takes time proportional to the length of the string; if you put it inside the condition of a loop, it will recalculate the size again and again, potentially slowing down your program significantly. Better save the result of strlen in a variable, and use that variable in the loop.

Did you read the second comment (the one about strlen)?

You can try changing this:

Code: Select all

          for(int i=0;i<strlen(s);i++)

for something like this:

Code: Select all

          for(int i=0, len = strlen(s);i<len;i++)
