List Comprehensions | HackerRank

Let's learn about list comprehensions! You are given three integers  and  representing the dimensions of a cuboid along with an integer . Print a list of all possible coordinates given by  on a 3D grid where the sum of  is not equal to . Here, . Please use list comprehensions rather than multiple loops, as a learning exercise.
Example




All permutations of  are:
.
Print an array of the elements that do not sum to .
Input Format
Four integers  and , each on a separate line.
Constraints
Print the list in lexicographic increasing order.
Sample Input 0:
1
1
1
2
Sample Output 0
[[0, 0, 0], [0, 0, 1], [0, 1, 0], [1, 0, 0], [1, 1, 1]]
Explanation 0
Each variable  and  will have values of  or . All permutations of lists in the form .
Remove all arrays that sum to  to leave only the valid permutations.
Sample Input 1
2
2
2
2
Sample Output 1
[[0, 0, 0], [0, 0, 1], [0, 1, 0], [0, 1, 2], [0, 2, 1], [0, 2, 2], [1, 0, 0], [1, 0, 2], [1, 1, 1], [1, 1, 2], [1, 2, 0], [1, 2, 1], [1, 2, 2], [2, 0, 1], [2, 0, 2], [2, 1, 0], [2, 1, 1], [2, 1, 2], [2, 2, 0], [2, 2, 1], [2, 2, 2]]

Solution

if __name__ == '__main__':
    x = int(input())
    y = int(input())
    z = int(input())
    n = int(input())
    print ([[a,b,c] for a in range(0,x+1) for b in range(0,y+1) for c in range(0,z+1) if a + b + c != n ])

Boxes through a Tunnel | HackerRank

You are transporting some boxes through a tunnel, where each box is a  parallelepiped , and is characterized by its length, width and height. The height of the tunnel   feet and the width can be assumed to be infinite. A box can be carried through the tunnel only if its height is strictly less than the tunnel's height. Find the volume of each box that can be successfully transported to the other end of the tunnel. Note: Boxes cannot be rotated. Input Format The first line contains a single integer  , denoting the number of boxes.  lines follow with three integers on each separated by single spaces    ,   and   which are length, width and height in feet of the  -th box. Constraints Output Format For every box from the input which has a height lesser than   feet, print its volume in a separate line. Sample Input 0 4 5 5 5 1 2 40 10 5 41 7 2 42 Sample ...

Array Manipulation | HackerRank

Image
Starting with a 1-indexed array of zeros and a list of operations, for each operation add a value to each of the array element between two given indices, inclusive. Once all operations have been performed, return the maximum value in your array. For example, the length of your array of zeros  . Your list of queries is as follows: a b k 1 5 3 4 8 7 6 9 1 Add the values of   between the indices   and   inclusive: index -> 1 2 3 4 5 6 7 8 9 10 [ 0 , 0 , 0 , 0 , 0 , 0 , 0 , 0 , 0 , 0 ] [ 3 , 3 , 3 , 3 , 3 , 0 , 0 , 0 , 0 , 0 ] [ 3 , 3 , 3 , 10 , 10 , 7 , 7 , 7 , 0 , 0 ] [ 3 , 3 , 3 , 10 , 10 , 8 , 8 , 8 , 1 , 0 ] The largest value is   after all operations are performed. Function Description Complete the function  arrayManipulation  in the editor below. It must return an integer, the maximum value in the resulting array. arrayManipulation has the fo...

String Validators | HackerRank

Python has built-in string validation methods for basic data. It can check if a string is composed of alphabetical characters, alphanumeric characters, digits, etc. str.isalnum() This method checks if all the characters of a string are alphanumeric  (a-z, A-Z and 0-9) . >>> print 'ab123'.isalnum() True >>> print 'ab123#'.isalnum() False str.isalpha() This method checks if all the characters of a string are alphabetical  (a-z and A-Z) . >>> print 'abcD'.isalpha() True >>> print 'abcd1'.isalpha() False str.isdigit() This method checks if all the characters of a string are digits  (0-9) . >>> print '1234'.isdigit() True >>> print '123edsd'.isdigit() False str.islower() This method checks if all the characters of a string are lowercase characters  (a-z) . >>> print 'abcd123#'.islower() True >>> print 'Abcd123#'.islower() False str....
