TESTING TROUBLE T__T

Question

import java.util.Scanner;
public class Security
{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
String S1 = input.nextLine();
String S2 = S1.replaceAll("x","");
char [] A = S2.toCharArray();

if(A[1]=='G'){System.out.println("quiet");}
else{System.out.println("ALARM");}
}
}
My code just thought 5/6 test cases. So I can't gain 100 exp as expected. Could someone give me an advice. Thanks a lot.

Answer 1

Good one.. RnT.Lee
But you lucky, if input contains like ex: "TGGGquot;, it Alarms...
Another approach is, read string, assign index values to G, T, $ variables and compare G is between or not..
Just saying for you to give a try that as practice..
Good luck for Next one...

Answer 2

Smart logic..
But I think, problem may contains inputs of any number of Gurads..
Ex:
GTG$

Answer 3

RnT.Lee
Check it in the code coach.. If not passed then reply here..
First approach is better but may not pass for G>1, so make it a special case.
2nd is also may works.. check ones..

Problem says to check G must be in between T&$ like T<G<$ or lt;G<T. You may check it any way..

Answer 4

RnT.Lee
Congrats..
But your fisrt code is fine for this case..
Are you changed approach..?

Answer 5

Jayakrishna🇮🇳 Maybe... :((( I'll try again.

Answer 6

Jayakrishna🇮🇳 How about this code that just be modified:
for(int i = 0; i<A.length; i++){
if(A[i]=='#x27;){
if(A[i+1]=='T'||A[i-1]=='T') {System.out.println("ALARM");}else{System.out.println("quiet");}}}

Answer 7

Here my attempts:
if(S2.contains("$GT")||S2.contains("TGquot;)) {System.out.println("quiet");}else{System.out.println("ALARM");}
But it just passed 5/6 test cases too.

Answer 8

@I'm done!! 😅
Test case No.6 that has the input is of the form "$GGGGT".

Answer 9

Jayakrishna🇮🇳
Here my attempts:
if(S2.contains("$GT")||S2.contains("TGquot;)||S2.contains("$GGGGT")) {System.out.println("quiet");}else{System.out.println("ALARM");} //There are only one "T" and one "quot;, so the String just need to contains one of the substrings above.
More over, my first code is just accidentally solved. It is not right for all of cases. Ex: GG$T or G$GT...
