Write a function named coinFlip that simulates repeatedly flipping a two-sided coin until a particular side (Heads or Tails) comes up several times consecutively (in a row).
Your function should accept two parameters, an integer k and a character side, where side is expected to be 'H' for Heads or 'T' for Tails.
You should keep simulating the flipping of the coin until k occurrences of the given side are seen consecutively.
For example, if the call is coinFlip(3, 'H') , you should flip the coin until Heads is seen 3 times in a row.
Here is an example output from the call of coinFlip(4, 'T'):
T H T H T T H T T H H T H H H H H T T T T
You got T 4 times in a row!
If a negative k is passed, and/or a side value is passed that is not 'H' or 'T', your function should throw an exception with the message k must be non-negative and side must be 'H' or 'T'.
Use Math.random to give an equal chance to a head or a tail appearing.
Each time the coin is flipped, what is seen is displayed (H for heads, T for tails), separated by spaces.
When k consecutive occurrences of the given side occur, a congratulatory message is printed.
Match our output format exactly.
