 Code Breakdown
 --------------
 line 2: setup a string
 line 3: create a stack of words, based on the sentence, but splitting the sentence by spaces
 line 4: loop over items in the stack, - for x in 0 to the length/size of the stack O(n) runtime.
 line 5: concatinates a space, plus a space, then pops the top word from the words stack
 line 6: returns everything in the backwards sentence, except for the 1st character.
         this is becaues we add a space to the start in line 5
