Find maximum occurring character from the given string
Max occurring character is the most frequent interview whiteboard question. Ok, there are so many of ways to handle this question and this is just one of them.
I have showed it with 6 characters as starting point and use those as reference. But you can extend that given object to hold as many characters as you want.

String Permutation Problem
The algorithm problem goes something like this:
If you are given a character and its possible substitution set, then write a function that would print all the permutation of its characters.
Given word “java”
Substitution Set =>
j [“J”, “7”]
a [“@”, “J”, “9”]
v [“V”, “^”]
Based on this, the possible permutations could be: J@V@, 7JV9..
Here is my approach using java
