+Task 1: "Only 100, please.
+
+You are given a string "123456789". Write a script that would insert "+"
+or "-" in between digits so that when you evaluate, the result should
+be 100."
+
+My notes: hmm.. looks like it might be combinatorial.  Is there a clever way?
+It's almost like a version of Countdown's number game (without * and /).
+
+Task #2: "Make it $200
+
+You have only $1 left at the start of the week. You have been given an
+opportunity to make it $200. The rule is simple with every move you can
+either double what you have or add another $1. Write a script to help
+you get $200 with the smallest number of moves.
+"
+
+My notes: doubling sounds like the way to go..  exhaustive breadth first
+search "try both options at every move" seems obvious but combinatorial growth
