hree animals stand next to each other by size, as follows: An Elephant, followed by a Hippo, followedby a Panda bear, [E, H, P ]. Your goal is to re-arrange them so that they are sorted in the oppositesize-based order. You are only allowed to switch positions of neighboring animals. Do not use Insertionor Merge sort. Try to use your own strategy to re-arrange the array.(a) How many operations do you need to reverse the order of the three animals?(b) Lets generalize the above. You have an array of n elements whose ordering you want to revers.Write pseudo code to do this.(c) How many operations do you need to reverse the ordering of an array of n? Your answer shouldbe a function of n.
