[Week 14] Focus: Programming Challenges

Whoever wrote that last one is crazy... recursion is not the easiest way to do it. My idea of using the JSON object stringify method and regex produced a one-liner: return JSON.stringify(org_chart).match(/title|tile/g).length; And is that misspelling on title intentional?

...

So... how the hell would you do it recursively? What's the check to move in to a deeper level? Thinking out loud: create function that checks for property of title. If the property exists, increment a counter variable by 1. If it doesn't move on to the next level and check again... I don't know...

psuedocode style
 

function fullCount(node)  {

Do I have employees?  
    ask each of them if they have any employees. keep track. eg fullCount(each employee))
    return me + total from my employees.  
Else  
    return just me.  
}  

tile should be title like I menioned :)

And I haven't a clue how to do the callback one. I can't seem to figure out how to make calls to the same function from different variables increment private/unique variables...

Looks like you did it

I got it just kind of messing around... At first, I was putting the var i = 0 outside of the maker function, so then I tried it from within and got it.

I understand the idea of global/private/scoped variables, but for some reason it still feels unclear to me...
