Studying for a Tech Interview Sucks, so Here's a Cheat Sheet to Help

This list is meant to be a both a quick guide and reference for further research into these topics. It's basically a summary of that comp sci course you never took or forgot about, so there's no way it can cover everything in depth. It also will be available as a gist on Github for everyone to edit and add to.

Data Structure Basics

###Array ####Definition:

• Stores data elements based on an sequential, most commonly 0 based, index.
• Based on tuples from set theory.

// run: swift speech.swift "東京特許許可局"
// build: xcrun -sdk macosx swiftc speech.swift && ./speech "東京特許許可局"
//
// for OSX, use NSSpeechSYnthesizer in AppKit,
// (for iOS, use AVSpeechSynthesizer in AVFoundation)

Zombie Error Message Xcode

Error message:

Build operation failed without specifying any errors. Individual build tasks may have failed for unknown reasons. 
One possible cause is if there are too many (possibly zombie) processes; in this case, rebooting may fix the problem. 
Some individual build task failures (up to 12) may be listed below.

1. Create a .gitattributes file:

Assuming you don’t already have one, create a file called .gitattributes in your project’s root directory.

2. Set the merge strategy to union:

Add the following line to your .gitattributes file.

This will tell git to merge using the union strategy, meaning it’ll keep both sides (theirs and ours).

func sumFromOne(upto n: Int) -> Int {

Regular expresions in swift (notes).

Special characters in literal strings, precede them by a backslash \ character.

This means the standard regular expression \. will appear as \\. in Swift code.

Capturing parentheses: are used to group part of a pattern, example 3(pm|am) would match the text 3 pm as well ass 3 am. The pipe character here | acts like an OR operator.

The question mark after capturing parentheses means that whatever is inside the parentheses is optional. Nov(ember)?, input could be Nov or November.

Create your SH code:

#!/bin/bash
echo "Stash App Code..."
cd <YOUR_PATH>
branchName=$(git branch | grep \* | cut -d ' ' -f2)
if [[ $branchName != *"fatal"* ]]; then
echo -e "You are on branch: "$branchName
echo "Let's save your work... /o.o/"
