            I would say CTF challenges are a good way to learn. https://tryhackme.com/ is a good place to start. Most of the rooms are aimed at beginners and it will give you a good understanding, of some of the programs you will use like nmap, burpsuite and wireshark. https://www.hackthebox.eu/ is a good place, when you are a bit more experienced.

            I have got the answer. Open the login page of CodeChef. Enter the username of your account and use Github password. You will get your account back. This account will not be linked with Github.

            Note: If you forgot your username you can possibly find it in your registered(Github) email id's mail inbox.

            How to remove the extra zeros from the output?
            Asked 2021-May-14 at 17:04

            I am trying to solve a problem from CodeChef. The problem statement is as follows.

            Pooja would like to withdraw X $US from an ATM. The cash machine will only accept the transaction if X is a multiple of 5, and Pooja's account balance has enough cash to perform the withdrawal transaction (including bank charges). For each successful withdrawal, the bank charges 0.50 $US. Calculate Pooja's account balance after an attempted transaction.

            Input: 42 120.00

            Output: 120.00

            For this input, I am getting an output of 120.000.00.

            ANSWER

            Answered 2021-May-14 at 17:04

            You are printing 120.00 via printf("%.2f", initial_balance); and after that printing uninitialized indeterminate value via printf("%.2f", final_balance);.

            Instead of the printing printf("%.2f", initial_balance); in the if statement, you should set the answer to final_balance like final_balance = initial_balance;.

            The game of billiards involves two players knocking 3 balls around on a green baize table. Well, there is more to it, but for our purposes this is sufficient.

            The game consists of several rounds and in each round both players obtain a score, based on how well they played. Once all the rounds have been played, the total score of each player is determined by adding up the scores in all the rounds and the player with the higher total score is declared the winner.

            The Siruseri Sports Club organises an annual billiards game where the top two players of Siruseri play against each other. The Manager of Siruseri Sports Club decided to add his own twist to the game by changing the rules for determining the winner. In his version, at the end of each round, the cumulative score for each player is calculated, and the leader and her current lead are found. Once all the rounds are over the player who had the maximum lead at the end of any round in the game is declared the winner.

            Unless I'm missing something, you don't need to store the scores for each round in an array at all.

            You only need a two element array, indexed by player number, to hold the total/accumulated scores

            Just remember the "best" round (largest lead) and the player that had it as you read in the data.

            Most probably you're trying to read input when there is no more input left to read and python raises an exception, the online judge in return gives the (NZEC) error. Try using raw_input() instead of input(). Comment back to let me know if it worked.

            This is a codechef beginner problem. I know it can be done in much easier ways, but I thought to try recursion here. My program is giving correct answer when I give only one input at a time, but when I run given testcases it only shows output for first two.

            There are few logical errors in your code, I'll try to point them one by one-

            1.) Remove line 47 because when something like this happens your main function will be stopped(return 0 stops the main function and thus program) and your program will not run for rest of the test cases. You can use boolean flag for that purpose.

            2.) You don't need the for loop inside main function, below code will consider all the cases.

            3.) If you understand the problem then first you always try to pick the dish with the maximum price and you want to pick it as many times as you can, so I'm writing your code in a better recursive manner(since you want to solve it recursively)-

            Link : https://www.codechef.com/LRNDSA01/problems/LAPIN

            Program description : Lapindrome is defined as a string which when split in the middle, gives two halves having the same characters and same frequency of each character. If there are odd number of characters in the string, we ignore the middle character and check for lapindrome. For example gaga is a lapindrome, since the two halves ga and ga have the same characters with same frequency. Also, abccab, rotor and xyzxy are a few examples of lapindromes. Note that abbaab is NOT a lapindrome. The two halves contain the same characters but their frequencies do not match. Your task is simple. Given a string, you need to tell if it is a lapindrome.

            The algorithm you implemented is both incorrect and very slow (even if it was correct). Since the input characters are limited to a..z, you could implement a fast algorithm by comparing the frequencies of letters in the left and right portions of the input text. An example implementation is below. The code assumes that the character codes of a..z are contiguous, which isn't guaranteed by the C standard.
