Let's practice manipulating some of Ruby's Flow Control mechanisms while working on a basic algorithm exercise.
Spend 20 minutes working on the first challenge. Implement the solution twice, using 2 of the following looping tools:
each
for
loopwhile
loopuntil
looploop
loop
Then spend 5 - 10 minutes recapping and sharing solutions for that exercise
Next spend 30 minutes working on the second challenge. Again, implement it twice using 2 of the available looping techniques.
