Given a list of coordinate pairs, output the Trapezoidal Riemann Sum of the values given between the first and last x-coordinates.
You will be given a sorted list of coordinate pairs, like this:
[
[1,2],
[3,5],
[5,11]
]
Note that x-coordinates will always be in increasing order, ys may not...

Draw an Ascii Grid
Given an integer n > 1, draw a grid composed of the characters: "-" "+" and "|". However, since I want the grid to look nice, the horizontal component should be 2 wide.
Trailing spaces for each line are not required.
Examples:
n = 2

Implement a cleave function
functional-programming
Think of cleave as the conceptual inverse of map. If map applies a function to each number in a list...
map([1, 2, 3], x -> x * 5) -> [5, 10, 15]
then cleave applies each function in a list to a number.
cleave(5, [x -> x * 2, x -> x - 1, x -> x ...
