Given an unsorted array of integers, sort them in such a way that all negatives come first, followed by zeroes, followed by all positives. 5,-6,8,0,4,-10,11 could become -6,-10,0,8,4,11 (does not have to be sorted into increasing order) What is the run time of this? Can we reduce the run time, if so, how (implement the new way)? Doing black box testing, how can we determine the run time? How can we determine if we have a memory leak?

Given a regular phone number dial pad, write code that will list out all the possible letter combinations that can be made given three numerical digits as input. For example, the base function would look like this: function numberToChars(int *numbers) { // would return an array of different character combinations // if input was 123 // output: adg, adh, adi, bdg, etc... }
