Combination of List
Instructions
Below are Instructions for this Kumite.
Introduction
Given the two list or arrays, filter and combine the numbers into one list or arrays. There will only be numbers in the list.
Requirements
- There will be no negative number in the list
- The list must be ordered in ascending order.
- There must be no repeating number in the list.
- It must support an empty list.
Test Samples
Below are the test sample for this excercise
# Multiple list should be able to combine into one list
combine_list([1,2,3],[4,5,6])
> [1,2,3,4,5,6]
# Final list should be sorted
combine_list([3,2,1,5],[6,8,7])
> [1,2,3,5,6,7,8]
# There must be no repeating number in the list
combine_list([4,5,6],[7,7,8])
>[4,5,6,7,8]
# The will be no negative number in the list
combine_list([4,5,8],[99,0,11,665,-245])
> [0,4,5,8,11,99,665]
