Problem Link to the original HackerRank problem Let’s learn about list comprehensions! You are given three integers x, y and z representing the dimensions of a cuboid along with an integer n. Print a list of all possible coordinates given by (i, j, k) on a 3D grid where the sum of i + j + k is not equal to n. Here: 0 <= i <= x; 0 <= j <= y; 0 <= k <= z; Please use list comprehensions rather than multiple loops, as a learning exercise. ...

Problem Link to the original HackerRank problem The included code stub will read an integer, n, from STDIN. Without using any string methods, try to print the following: 123...n Note that “...” represents the consecuvitve values in between. Example n = 5 Print the string 12345 Input Format The first line contains an integer n. Constraints 1 <= n <= 150 Output Formats 1 <= n <= 150 Input Format ...

Problem Link to the original HackerRank problem An extra day is added to the calendar almost every four years as February 29, and the day is called a leap day. It corrects the calendar for the fact that our planet takes approximately 365.25 days to orbit the sun. A leap year contains a leap day. In the Gregorian calendar, three conditions are used to identify leap years: The year can be evenly divided by 4, is a leap year, unless: The year can be evenly divided by 100, it is NOT a leap year, unless: The year is also evenly divisible by 400. Then it is a leap year. This means that in the Gregorian calendar, the years 2000 and 2400 are leap years, while 1800, 1900, 2100, 2200, 2300 and 2500 are NOT leap years. Source ...
