      For this week I did 2 more coding problems. The first one I did was more challenging and its called isIsomorphic. Lets say we have 2 strings and a holds the value of the first string and b holds the value of the second string. Two strings are isomorphic only if you can replace all the characters in a with all the characters in b. That means that all the occurrences of a character in a string a must map directly back to another character in the string b. They must back and forth together in order for it to be isomorphic. For example the string abb is isomorphic with the string cdd. That is because for every a character you can replace it with the character c. Also every b character you can replace it with the letter d. In our problem we can also assume that both strings that are given will always be of equal length.      When I first started the problem right away I thought to create a dictionary. We could loop through the strings and map every character in string a with string b.

      For this weeks assignment I will demonstrate a technique I actually just learned this semester in one of my csc classes. It is the idea of pointers. I am currently learning about C. The interesting part about C is the concept of pointers that I did not realize we were already using in java. A pointer is a a variable that holds the memory of an address location in your memory. Instead of actually holding a value it holds a location that you can use and pass as a parameter to a function if you want to edit that variable in another function. If you were just to pass a value as a parameter the function would only get a copy of the value and if you try to edit it in the function the function that it got called from wouldnt update. I will explain what is going on in my code for an example.     The program I wrote is dice rolling game. I only posted my main and my player turn function to show how pointers work. In C the first thing you have to do is declare your prototypes. My prototype

      For this weeks assignment I decided to learn how to make a game using Python. I have been looking up online how to get better at coding and other than doing coding challenges its useful to create real world projects to put everything together. I learned so much just from doing this project that I didn't know from just doing coding challenges. Now this is 147 lines of code so I wont explain every single detail but I did leave comments on all of my code so you can go through it and understand what each block of codes adds to the game.I will also upload a video at the end of this page so you can see the game working in real time.     The first thing I had to do is import a built in library in Python called Turtle. It allows you to draw different objects and animations on to your screen. Once I installed Turtle I created a variable holding the Turtle.Screen function that allows me to create a screen that pops up. Once I did that I changed different attributes of my screen such as
