You are given a mathematical expression containing integers and the basic operations: *,+,-, /. Find
the number of unique results that can be obtained by parenthesizing the expression differently. i.e.,
by changing the order of evaluation of the operations. Note that all operations are integer operations.
For example, if the input is 2 ∗ 3 + 6/2, your output should be 4.

3) Do your homework first. Only post the part of the script you're having trouble with! There are generally two types of people- ones that simply dump their entire page or problem and expect everyone to spend hours solving everything for them, and those that do their own homework first, and only ask very specific, manageable questions. The later invariably gets more and better responses from others. When you're lazy, do not expect us to be hardworking for you.

As an example, lets say you're working on a long script that uses the "switch" statement of JavaScript, and it's returning errors. You could either:

i) Post the entire script and simply say "Please debug this script for me!"
ii) Or, localize the problem yourself first and post instead "Can someone tell me the syntax of the switch statement in JavaScript?"

The second question will get a LOT more quality responses, as it is concise, manageable, and not overwhelming. Remember, ask for the world, and you'll get nothing. Ask for a little, and you'll get a lot.
