1 Create a data structure that efficiently supports the stack operations (pop and push) and also return the maximum element. 2  Assume the elements are integers or reals so that you can compare them. 3  Hint: use two stacks, one to store all of the elements and a second stack to store the maximums. 4  Tag systems.
Deep-Sea Mermaid Lake Mermaids Lake mermaids, sometimes known as Freshwater mermaids, live in freshwater and are built for chamouflage and sometimes live partially on land.
The earliest known mermaid legends come from Syria around 1000 B.C. where the Syrian goddess Atargatis dove into a lake to take the form of a fish, but the powers there would not allow her give up her great beauty, so only her bottom half became a fish and she kept her top half in human form.ater tales in the mythology of mermaids stem from Homer's epic The Odyssey, where some mythologists believe the Sirens to have been in mermaid form. This was an extremely popular version of the mermaid throughout history.
