Unfair Hurdles

Unfair hurdles are hurdles which are either too high, or way too close together.

Create a function which takes in a list of strings, representing hurdles, and return whether they are unfair. For the purposes of this challenge, unfair hurdles are:

• At least 4 characters tall.
• Strictly less than 4 spaces apart.

Examples

# Hurdle are good distance apart but are way too tall.

is_unfair_hurdle([
  "#    #    #    #",
  "#    #    #    #",
  "#    #    #    #",
  "#    #    #    #"
]) ➞ True

# Hurdles are a fine height but are way too close together.

is_unfair_hurdle([
  "#  #  #  #",
  "#  #  #  #",
  "#  #  #  #"
]) ➞ True

# These hurdles are mighty splendid.

is_unfair_hurdle([
  "#      #      #      #",
  "#      #      #      #"
]) ➞ False

Notes

• Hurdles will be represented with a hashtag "#".
• There will be the same spacing between hurdles.
• Hurdles are always as high as the length of the list.
• Hurdles are always evenly spaced.
