2013/07/24 Interview Question: Reduced String

A reduced string is a string with all repeating letters condensed into one. The exercise was writing a function that compares two strings and returns true if their reduced string is the same.

What I did for this was…

1. have a pointer to the start of each string
2. compare the two letters

1. if they’re not the same, return false

for each string, advance the pointer until it lands on a different character.

repeat steps 2-3 until null terminated.

1. if only one was terminated and the other hasn’t, return false

return true

And that’s it. Better ideas? Corrections (I might have mistyped, it’s early)?
