- Find and use built-in Ruby methods to solve challenges
Implement Array#pad and Array#pad!. Each method accepts a minimum size (non-negative integer) and an optional pad value as arguments.
If the array's length is less than the minimum size, Array#pad should return a new array padded with the pad value up to the minimum size.
For example,
[1,2,3].pad(5)should return
[1,2,3,nil,nil]And
[1,2,3].pad(5, 'apple')should return
[1,2,3,'apple', 'apple']If the minimum size is less than or equal to the length of the array, it should just return the array.
That is, [1,2,3].pad(3) should return [1,2,3].
my_array.pad(0) should always return an array equal to my_array. Array#pad should always return a new object, i.e., it should be non-destructive.
Array#pad! behaves identically to Array#pad except that it modifies the underlying array.
