Chapter 19, Problem 1RQE
Explanation of Solution
LIFO:
LIFO stands for “Last In First Out”.
- The item which is inserted at last, can be retrieved first.
- The example for LIFO implementation is “stack” which is a type of container.
- The elements can be inserted and retrieved at any one end of the stack. A stack can perform two operations. They are:
- Push – Inserting an element inside a stack.
- When the first element is pushed into the stack, the element will be at the “top” the stack. When the second element is added, the first element is pushed down and the second element will be at the top position, like this it goes on until the element which pushed at last will be at the top of the stack.
- Pop – Deleting an element from the stack.
- The element which is inserted at last will be deleted first.
- Push – Inserting an element inside a stack.
Example: Cookies in a container.
The baker arranges the cookies one by one in a container in which the lastly inserted cookie is taken out first from the container.

For simplification, only consider cutting the rope at an integer position by the meter metric. Each cut has a cost associated with it, c(m), which is the cost of cutting the rope at position m. (You can call c(m) at any time to return the cost value.) The goal is to cut the rope into k smaller pieces, minimizing the total cost of cutting. B Provide the pseudo-code of your dynamic programming algorithm f(n,k) that will return the minimum cost of cutting the rope of length n into k pieces. Briefly explain your algorithm.
