Member functions in stack template adapter class: The member functions in stack templates are given below: “s.size()”: This function is used to returns the number of elements in the stack. “s” is object of stack template adapter class. “s.empty()”: This function is used to returns “true” if the stack is empty. Otherwise, this function returns “false”. “s.top()”: This function is used to returns top value of the given stack. “s.push(Value)”: This function is used to insert a “Value” to the top of stack. “s.pop()”: This function is used to removes the top value of the stack. In stack, the “pop” function is a void function. So, it does not return the removed value. “st1 == st2”: This function is used to check whether the two stacks are equal or not. If “st1.size == st2.size”, then returns “true”. That is if the number of elements in stack “st1” is equal to corresponding elements in stack “st2”. Otherwise, returns “false”.

Program Plan Intro

Member functions in stack template adapter class:

The member functions in stack templates are given below:

“s.size()”:

This function is used to returns the number of elements in the stack.

“s” is object of stack template adapter class.

“s.empty()”:

This function is used to returns “true” if the stack is empty.

Otherwise, this function returns “false”.

“s.top()”:

This function is used to returns top value of the given stack.

“s.push(Value)”:

This function is used to insert a “Value” to the top of stack.

“s.pop()”:

This function is used to removes the top value of the stack.

In stack, the “pop” function is a void function.

So, it does not return the removed value.

“st1 == st2”:

This function is used to check whether the
two stacks are equal or not.

If “st1.size == st2.size”, then returns “true”. That is if the number of elements in stack “st1” is equal to corresponding elements in stack “st2”.

Otherwise, returns “false”.

Design a dynamic programming algorithm for the Longest Alternating Subsequence problem described below: Input: A sequence of n integers Output: The length of the longest subsequence where the numbers alternate between being larger and smaller than their predecessor The algorithm must take O(n²) time. You must also write and explain the recurrence. Example 1: Input: [3, 5, 4, 1, 3, 6, 5, 7, 3, 4] Output: 8 ([3, 5, 4, 6, 5, 7, 3, 4]) Example 2: Input: [4,7,2,5,8, 3, 8, 0, 4, 7, 8] Output: 8 ([4, 7, 2, 5, 3, 8, 0,4]) (Take your time with this for the subproblem for this one)

Design a dynamic programming algorithm for the Coin-change problem described below: Input: An amount of money C and a set of n possible coin values with an unlimited supply of each kind of coin. Output: The smallest number of coins that add up to C exactly, or output that no such set exists. The algorithm must take O(n C) time. You must also write and explain the recurrence. Example 1: Input: C24, Coin values = = [1, 5, 10, 25, 50] Output: 6 (since 24 = 10+ 10+1+1 +1 + 1) Example 2: Input: C = 86, Coin values = [1, 5, 6, 23, 35, 46, 50] Output: 2 (since 86 = 46+35+5)

Design a dynamic programming algorithm for the Longest Common Subsequence problem de- scribed below Input: Two strings x = x1x2 xm and y = Y1Y2... Yn Output: The length of the longest subsequence that is common to both x and y. . The algorithm must take O(m n) time. You must also write and explain the recurrence. (I want the largest k such that there are 1 ≤ i₁ < ... < ik ≤ m and 1 ≤ j₁ < ... < jk ≤ n such that Xi₁ Xi2 Xik = Yj1Yj2 ··· Yjk) Example 1: Input: x = 'abcdefghijklmnopqrst' and y = 'ygrhnodsh ftw' Output: 6 ('ghnost' is the longest common subsequence to both strings) Example 2: Input: x = 'ahshku' and y = ‘asu' Output: 3 ('asu' is the longest common subsequence to both strings)
