Exercises on Stack (using Array)
Assume S is a STACK and it is having n elements. Write C language code to implement the following queries using PUSH and POP operations
1)Delete the mth element of the stack S from the top (m<n) without missing its top m-1 elements.
2)Retain only the elements in the odd position of the stack S and pop out all even positioned elements.
( Note: You can use temporary stack to implement (a) and (b) )

- 1. Compare and contrast the implementations of the stack data structure using arraysand linked lists.a) How are they different?b) What are the run times of the stack operations for each implementation?c) When would one method be preferred over the otherPP 12.4 The array implementation in this chapter keeps the top variablepointing to the next array position above the actual top of thestack. Rewrite the array implementation such that stack[top] isthe actual top of the stack. PP 12.5 There is a data structure called a drop-out stack that behaves likea stack in every respect except that if the stack size is n, whenthe n + 1 element is pushed, the first element is lost. Implement adrop-out stack using an array. (Hint: A circular array implementation would make sense.)Given the following sequence of characters: DA&T!A ST*R&U!CT!&UR*ES. Consider the stack data structure, supporting two operations push and pop. Suppose that for the above sequence, each letter (such as DATA STRUCTURES) corresponds to a push of that letter onto the stack, each exclamation mark(!) corresponds one pop operation on the stack, each ampersand (&) corresponds one peep operation on the stack and each asterisk (*) corresponds two pop operations on the stack. Show the sequence of values returned by the pop operations. Also, display the remaining elements in the stack after all the push and pop operations.
