String Split and Join
In Python, a string can be split on a delimiter. Example: >>> a = "this is a string" >>> a = a.split(" ") # a is converted to a list of strings. >>> print a ['this', 'is', 'a', 'string'] Joining a string is simple: >>> a = "-".join(a) >>> print a this-is-a-string Task: You are given a string. Split the string on a " " (space) delimiter and join using a - hyphen. Input Format: The first line contains a string cons

Sam's house has an apple tree and an orange tree that yield an abundance of fruit. Using the information given below, determine the number of apples and oranges that land on Sam's house. In the diagram below: The red region denotes the house, where s is the start point, and t is the endpoint. The apple tree is to the left of the house, and the orange tree is to its right. Assume the trees are located on a single point, where the apple tree is at point a , and the orange tree is a

Most HackerRank challenges require you to read input from stdin (standard input) and write output to stdout (standard output). One popular way to read input from stdin is by using the Scanner class and specifying the Input Stream as System.in. For example: Scanner scanner = new Scanner(System.in); String myString = scanner.next(); int myInt = scanner.nextInt(); scanner.close(); System.out.println("myString is: " + myString); System.out.println("myInt is: " + myInt); The code abov

In this challenge, we test your knowledge of using if-else conditional statements to automate decision-making processes. An if-else statement has the following logical flow: Wikipedia if-else flow chart Source: Wikipedia Task Given an integer, n, perform the following conditional actions: If is odd, print Weird If is even and in the inclusive range of 2 to 5, print Not Weird If is even and in the inclusive range of 6 to 20 , print Weird If is even and greater than 20 , print
