Decreasing Numbers
Numbers whose digits, when read from left to right, are never
greater than the previous digit. See below some examples of
decreasing numbers:
1111
654321
999887521
Create a function that takes a number n and returns total
occurrences of all the increasing or decreasing numbers in the
range 1 - 10^n.
Examples
1
incDec (0)
// 10^0
= 1
// 1 is both increasing and decreasing.
incDec (1) → 10
// 10^1 = 10
// [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] are both increasing
incDec (3)
475
