@@ -2,15 +2,41 @@
A complex number is a number in the form `a + b * i` where `a` and `b` are real and `i` satisfies `i^2 = -1`.
`a` is called the real part and `b` is called the imaginary part of `z`.
The conjugate of the number `a + b * i` is the number `a - b * i`.
The absolute value of a complex number `z = a + b * i` is a real number `|z| = sqrt(a^2 + b^2)`. The square of the absolute value `|z|^2` is the result of multiplication of `z` by its complex conjugate.
The sum/difference of two complex numbers involves adding/subtracting their real and imaginary parts separately:
`(a + i * b) + (c + i * d) = (a + c) + (b + d) * i`,
`(a + i * b) - (c + i * d) = (a - c) + (b - d) * i`.
Multiplication result is by definition
`(a + i * b) * (c + i * d) = (a * c - b * d) + (b * c + a * d) * i`.
The reciprocal of a non-zero complex number is
`1 / (a + i * b) = a/(a^2 + b^2) - b/(a^2 + b^2) * i`.
Dividing a complex number `a + i * b` by another `c + i * d` gives:
`(a + i * b) / (c + i * d) = (a * c + b * d)/(c^2 + d^2) + (b * c - a * d)/(c^2 + d^2) * i`.
Exponent of a complex number can be expressed as
`exp(a + i * b) = exp(a) * exp(i * b)`,
and the last term is given by Euler's formula `exp(i * b) = cos(b) + i * sin(b)`.
Implement the following operations:
- addition, subtraction, multiplication and division of two complex numbers,
- conjugate, absolute value, exponent of a given complex number.
Assume the programming language you are using does not have an implementation of complex numbers.

# Nucleotide Count
Given a DNA string, compute how many times each nucleotide occurs in the string.
Given a single stranded DNA string, compute how many times each nucleotide occurs in the string.
DNA is represented by an alphabet of the following symbols: 'A', 'C',
'G', and 'T'.
Each symbol represents a nucleotide, which is a fancy name for the
particular molecules that happen to make up a large part of DNA.
Shortest intro to biochemistry EVAR:
The genetic language of every living thing on the planet is DNA.
DNA is a large molecule that is built from an extremely long sequence of individual elements called nucleotides.
4 types exist in DNA and these differ only slightly and can be represented as the following symbols: 'A' for adenine, 'C' for cytosine, 'G' for guanine, and 'T' thymine.
Here is an analogy:
- twigs are to birds nests as
- nucleotides are to DNA and RNA as
- amino acids are to proteins as
- sugar is to starch as
- oh crap lipids
- nucleotides are to DNA as
- legos are to lego houses as
- words are to sentences as...
I'm not going to talk about lipids because they're crazy complex.
So back to nucleotides.
DNA contains four types of them: adenine (`A`), cytosine (`C`), guanine
(`G`), and thymine (`T`).
RNA contains a slightly different set of nucleotides, but we don't care
about that for now.

@@ -5,41 +5,39 @@ Detect palindrome products in a given range.
A palindromic number is a number that remains the same when its digits are
reversed. For example, `121` is a palindromic number but `112` is not.
Given the definition of a palindromic number, we define a palindrome _product_
to be the product `c`, such that `a * b = c`, where `c` is a palindromic number and
`a` and `b` are integers (possibly, but _not_ necessarily palindromic numbers).
Given a range of numbers, find the largest and smallest palindromes which
are products of numbers within that range.
For example, the palindromic number 9009 can be written as the palindrome
product: `91 * 99 = 9009`.
It's possible (and indeed common) for a palindrome product to be the product
of multiple combinations of numbers. For example, the palindrome product `9` has
the factors `(1, 9)`, `(3, 3)`, and `(9, 1)`.
Write a program that given a range of integers, returns the smallest and largest
palindromic product within that range, along with all of it's factors.
Your solution should return the largest and smallest palindromes, along with the
factors of each within the range. If the largest or smallest palindrome has more
than one pair of factors within the range, then return all the pairs.
## Example 1
Given the range `[1, 9]` (both inclusive)...
The smallest product is `1`. It's factors are `(1, 1)`.
The largest product is `9`. It's factors are `(1, 9)`, `(3, 3)`, and `(9, 1)`.
And given the list of all possible products within this range:
`[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 14, 16, 18, 15, 21, 24, 27, 20, 28, 32, 36, 25, 30, 35, 40, 45, 42, 48, 54, 49, 56, 63, 64, 72, 81]`
The palindrome products are all single digit numbers (in this case):
`[1, 2, 3, 4, 5, 6, 7, 8, 9]`
The smallest palindrome product is `1`. Its factors are `(1, 1)`.
The largest palindrome product is `9`. Its factors are `(1, 9)` and `(3, 3)`.
## Example 2
Given the range `[10, 99]` (both inclusive)...
The smallest palindrome product is `121`. It's factors are `(11, 11)`.
The largest palindrome product is `9009`. It's factors are `(91, 99)` and `(99, 91)`.
The smallest palindrome product is `121`. Its factors are `(11, 11)`.
The largest palindrome product is `9009`. Its factors are `(91, 99)`.
