Update ReverseString.java

066dd615a6 Update ReverseString.java
Using recursion for reversing a String serves us no benifit. It places extra load on the stack, and it is less efficient than doing so iteratively. I understand now that we can not use built in reverse function, but using recursion is still the worst way we could do the task of String reversal. Everytime we call the reverse method we are placing an extra frame on our stack. This uses space. We also create another string that we are appending our result to with the recursive solution, which is slow because under the hood, Java will create a new empty String and then append each character to the new String, one char at a time. If we do this for each character, then asymtotically we now have time complexity of O(n^2).  Recursion in this case also does not make our solution "simpler" or "more elegant". We want to use recursion when it is advantageous to do so....like traversing trees

149e5d2abc Update Factorial.java
The factorial method can be simplified to 2 lines, which I believe is easier to read. Also, in previous version, if user enters two negative numbers back to back, the program crashes. We need a while loop to prompt the user until they actually enter the correct input, instead of only prompting them once. Also, if user enters a character instead of an integer, program crashes with no error message. We should fail more gracefully.

Changed loop from "for" to "do-while". Added decrement at end of do loop to decrease size of array tested after each iteration.
