Last week we were discussing options to perform a map operation a hash. For example in ruby from symbols to strings. But, really this could be generalized. Your mission, should you choose to accept it is to write a function that takes a hash and performs a map operation on the keys.

You may do this in whatever language you choose the example is just in ruby.

Example

myHash = {
  'a' => 1,
 'b' => 2,

Write a simple way of adding a before filter onto a given method of a class.

Here is some Psudo code for you as an example of the functionalty I'm looking for.

a = new AClass;

a.talk();
// Logs:
// "Hello"

2 + 2 = 5

You've recently been transfered from Product Development to the newly formed Department of Truth.

People being 'educated' by your department don't belive that 2 + 2 = 5. You need to prove it to them. Write a little program that seemingly adds 2 + 2 and outputs 5.

Use some globals, leak some memory; more creative / nefarious is better. You may use whatever language or bad practices you feel are appropriate for this problem.

We have a grid of mostly 0s there will be one 1. Write a function that returns the position of the 1 relative to the bottom left of the grid.

For example:

grid = [[0, 0, 0],
        [0, 0, 0],
        [0, 0, 1]]

findIt(grid) # => [2, 0]

Array.prototype.bob = function(thing) {
    
    var result = this.slice(0);
    
    result.reverse();
    

    if (typeof thing !== "undefined" && thing !== null) {
        
        for (var i = 0; i < result.length; i++) {

$("img").get().reduce(function(reduction, item){
    if ($(item).parents('.gmail_quote, .gmail_extra').length === 0) {
        reduction.push(item);
        return reduction;
    }
}, [])
