like wow might be a reader has a knack xxx and if you want to you sort of the funky off toward each notation that's also in the book why allows you to do iteration over an iterator on the kind of a stylized form that's fine too but within stress that in class so i'm not constructed here while they later have an excellent i'll just get back to calgary yet dot max and then i want to see is this ke equal to the value rights are not going to stressor hatch map concept which the goldberg something open the hatch map and so i have streamed value equals map dot debt and what i'm going to get from the map is whatever matches that keep so if mike he happened to be alice over here i don't get the value which is out was out of that then i'll just keep writing the rest of it over here were almost died celebrate here we just safety at sea the particular value that i got habits to match the key now it's going to stress the concept of strings rights are all these kinds of things fit together uh... value dot equals clean which means that value equals the key value then i print out of the screen vicki i could find out the value to that is about the same at this point but that's the whole deal that's the end of my wild and pass the end of my so that's kind of the idea right this was not particularly earth-shattering but it stresses a bunch of concept unless you're a member of my cool things
