+1. You should have a function name `pyramid` that takes three arguments.
+1. The first argument should be a string representing the pattern character to repeat in your pyramid.
+1. The second argument should be an integer representing the number of rows in the pyramid.
+1. The third argument should be a Boolean value.
+1. `pyramid` should return a string in which the pattern character is repeated and arranged to form a pyramid having the vertex facing upwards when the third argument is `false`.
+1. When the third argument is `true` the pyramid should have the vertex facing downwards.
+1. The vertex row should have a single pattern character, and each other row should have two pattern characters more than the previous one.
