Write a method that returns the "flopped" version of the input array 'nums'. A "flopped" array is one such that elements of the array are replaced with the highest valued element that has occurred so far in the array. For example, the array {5,7,2,3,8,11,4,1}, when "flopped" becomes {5,7,7,7,8,11,11,11}. The reason is that by the time you get to index 0, the highest value that happened so far is 5. But then when you get to index 1, the highest value so far becomes 7. Since index 2 and 3 are less than 7, they get replaced with 7 because that is the highest value so far. This process continues through the remainder of the array. Look at the test data for additional examples. Please note that the input array 'nums' can contain ANY number of numbers AND can contain any valid integers.
