Whereas the unbounded stack has no such limits, could you perhaps elaborate on how this works?
find the attachement for the question
You are allowed to operate on a stack WORK and a temporary stack TEMP (ifneeded) supporting their ADT operations of PUSH (S,X), POP (S, X) andEMPTYSTACK (S) only, where X represents an element/variable to be pushed in orpopped out of the stack and S represents a stack. You are also permitted to use onevariable if needed to carry out the operations.i) Given n distinct random numbers that are to be pushed into WORK, how canyou find the minimum element that was pushed into it? You are permitted to use alone variable.ii) Given n distinct random numbers that are to be pushed into WORK, how canyou find the maximum element that was pushed into it, all the while ensuring thatthe elements stored in WORK are in their descending order with the maximumelement beginning at the bottom of stack? You are permitted to use a lone variableand a temporary stack TEMP.iii) Given an array A[1: n] of distinct random numbers how can you obtain thesorted list in the array, making use of stacks alone?
Q7 and 9 Please explain your answer
S1 and S2 are two sorted stacks of n and m numbers sorted in decreasing order, with their top items pointing to the smallest in their lists, respectively. Create a stack MERGE that merges the items in stacks S1 and S2, so that at the conclusion of the merge, all of the elements in S1 and S2 are available in MERGE in decreasing order, with the largest element at the top.Keep in mind that the number of components in stack MERGE is (n + m).
