Question

I failed test cases 3, 5, 6. Please help

My code:
https://code.sololearn.com/cfhNc3RxRLb7/?ref=app

You are in charge of security at a casino, and there is a thief who is trying to steal the casino's money! Look over the security diagrams to make sure that you always have a guard between the thief and the money!
There is one money location, one thief, and any number of guards on each floor of the casino.

Task:
Evaluate a given floor of the casino to determine if there is a guard between the money and the thief, if there is not, you will sound an alarm.

Input Format:
A string of characters that includes $ (money), T (thief), and G (guard), that represents the layout of the casino floor.
Space on the casino floor that is not occupied by either money, the thief, or a guard is represented by the character x.

Output Format:
A string that says 'ALARM' if the money is in danger or 'quiet' if the money is safe.

Sample Input:
xxxxxGxx$xxxT

Sample Output:
ALARM

Answer 1

____ your program assumes that there always would be a guard or thief after encountering money, and gives out no output when there isn't.

Example of an input where your program fails is : TG$
where according to question the output should be "quiet" but your program gives out no output.

In this case, a simple fix is to print "quiet" if the control reaches the end of your program 👇

Answer 2

____ Here's what I have done:

#include <stdio.h>

int main() {
char a[40];
fgets(a, 40, stdin);
int x=0, y=0;
for (int i=0;a[i];i++) {
if (a[i] == '#x27;) x++;
else if (a[i] == 'T') y++;
else if (a[i] == 'G') x = y = 0;
if (x && y) {
puts("ALARM");
return 0;
}
}
puts("quiet");
return 0;
}

// Here, I've used 'x' and 'y' as flags

// Hope this helps

Answer 3

Calvin Thomas Thank you for the code, but I want to know why my code failed if possible.

Answer 4

____ I've mentioned it in the comments.

Answer 5

Arsenic Calvin Thomas Thank you so much. It's now working.

Answer 6

import re

casino = 'T$xxxxxxxxGxx'

mod = re.sub('x','',casino)

check, check2, check3 = '$GT', 'TG#x27;, 'T$G'

Here's what I have done 100XP

if (check not in mod or check2 not in mod) and (check in mod): print('quiet')
else: print('ALARM')

Answer 7

Calvin Thomas I updated the code. Though 2 cases are passed, #3 still failed.
