Calculate the number of horns on a *unicorn*!
And I'm talking about a unicorn with not more than one horn on it!
Given the number x, y must be the summation of all integers from 1 to 2^x.
For instance if x=2 then y must be 1+2+3+4=10.
Return a list of all values (sorted smallest to largest) that appear exactly three times in the input vector x. So if
x = [1 2...
Return 1 if the input is sorted from highest to lowest, 0 if not.
1:7 -> 0
[7 5 2] -> 1
Given an hourly wage, compute an annual salary by multiplying the wage times 40 and times 50, because salary = wage x 40 hours/w...
If you have two small strings, like 'a' and 'b', return them put together like 'ab'.
'a' and 'b' => 'ab'

Given n, find the sum of the digits that make up 2^n.
Input n = 7
Output b = 11
since 2^7 = 128, and 1 + ...

Given an input vector x, find all elements of x less than 0 or greater than 10 and replace them with NaN.
Given a circular pizza with radius _z_ and thickness _a_, return the pizza's volume. [ _z_ is first input argument.]
Triangle numbers are the sums of successive integers. So 6 is a triangle number because
6 = 1 + 2 + 3
which can be displa...
Regardless of input, output the string 'yes'.
Given the input n, return true if n is odd or false if n is even.
Given an integer n, make an n-by-n matrix made up of alternating ones and zeros as shown below. The a(1,1) should be 1.
Find the sum of all the numbers of the input vector x.

In MATLAB, you create a vector by enclosing the elements in square brackets like so:
x = [1 2 3 4]
Commas are optional, s...
