In this laboratory work, the student should implement the following algorithm using the linked-list implementation of the queue structure. String-Corrector-Algorithm Repeat Get a symbol from the user If symbol is an alphabet, then If it is a lower-case alphabet, then Convert it to upper case End-if Insert it to the queue Else-if symbol is a digit, then Discard it Else-if symbol is a punctuator, then Discard it Else-if symbol is a white-space character, then Insert a space character to the queue Else /* is an unrecognized character */ Discard it End-if Until symbol is different than the newline character (enter key) While queue is not empty, do Remove a character from the queue Display it on the screen End-while

Heap Sort

A Heap is a type of data structure that is built on trees. It's a binary tree that's virtually complete. Except for the very bottom level, all levels of the tree must be filled in a heap. The last (bottom) level should be filled from left to right. The heap data structure is used for the efficient implementation of priority queues.Heap can be of two types:
