Problem 60221. Battery Charge Indicator

Write a function called battery_charge that visually represents the charge of a battery.
The function takes an integer parameter percentage between 0 and 100 representing the battery charge percentage. It returns an array bars where each element contains a single character (visually representing the battery charge).
The array starts with '[', ends with ']', and contains from 0 to 10 characters '❚' or ' ' (space) to visually represent the battery charge. The number of '❚' characters is rounded, meaning that for percentages like 9% and 11%, only one ❚ will be used.
