Data Searching and Binary Search
... Basic Operations for Tables Abstractly, a table is a mapping (function) from keys to values. Given a search key k, table search has to find the table entry (k, v) containing that key. After the search, one may: • Retrieve the found entry (k, v), e.g., to process v; • Remove, or delete the found entr ...

... Now, let us look at one more example, how do you append one node to the end of a list? So, first we will check that the node is pointing to a non null node. If it is pointing to a null node that is nothing to be done. So, there is nothing to be appended,. So, you have returned. Now, if there no need ...
