List comprehension hackerrank solution in python

  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 ...
