Background The marketing team at CodeSignal would like to know how many users there are in each Coding Score range for standardized tests like the General Coding Assessment, so that they can share that information on our website. They've asked you to create a report containing that information.
Your Mission
As input, you are given a list of scores. Coding Score can be anywhere between 300 and 850. For the purpose of this task, levels are defined in the following way:
Poor: 300-599 Fair: 600-699 Good: 700-749 Excellent: 750-799 Elite: 800 Calculate how many users are there in each level, then return a list of strings where each string represents a level and the percentage of users who fall within that range formatted like LevelName: XX. XXX Percentages should be displayed with two decimal points of precision. Levels should be sorted in decreasing order of those numbers, omitting any levels that have no users. In case of a tie the higher level should appear first For example, if you had this input... [330, 723, 750, 825] For example, if you had this input... [330, 723, 730, 825] ...then you should return the following: [ Good: 50.00%', Elite: 25.00%', Poor: 25.00% ] [execution time limit] 4 seconds (py3) • [input] array. integer scores An array of integers in the range [300, 850] [output] array. string An array of strings formatted like LevelName: XX.
