Designing Rugs

Write a function that accepts the height and width (m, n) and an optional proc s and generates a list with m elements. Each element is a string consisting of either:

• The default character (hash #) repeating n times (if no proc is given).
• The character passed in through the proc repeating n times.

Examples

make_rug(3, 5, '#') ➞ [
  "#####",
  "#####",
  "#####"
]

make_rug(3, 5, '$')  ➞ [
  "$$$$$",
  "$$$$$",
  "$$$$$"
]

make_rug(2, 2, 'A')  ➞ [
  "AA",
  "AA"
]

Notes

You can set a value for the parameter when creating the function e.g. def func(x = 3)
