#1.)

- isOdd(n)

Write the function isOdd that takes a single parameter (n) as input and returns the boolean value True if (n) Is an odd integer and False if Otherwise.

#2.)

- nOdd(t)

Write the function nOdd that takes a tuple (t) and returns an integer, the number of odd integers in the tuple.

#3.)

-overlap(a1, a2, b1, b2)

Write the function overlap that takes four integers a1, a2, b1, b2, defining two closed intervals [al, a2] and [b1, b2] of the real number line, and returns True if these two closed intervals overlap (even if at only one value) and False otherwise. If al > a2, then the interval (al,a2] is empty. If b1 > 'b2', then the interval [b1,b2] is empty. Both intervals are closed, so contain their endpoints.

#4.)

- isRightTri

Write the function isRightTri that takes three vertices of a triangle A in 2D, each vertex represented sing a tuple of two floats, and returns the Boolean True if A is a right triangle and False otherwise.

#5.)

- smallerThanIndex (L)

Write the function smallerThan Index that takes a list of integers and returns an integer, the nu integers in the list whose value is smaller than its index.
