Smart cards:
Smart card also called as chip cards is a physical card that has integrated chip embedded in the card. This chip is used to store the data and controls access to the resources.
- It is made of metal or plastic and is commonly used in credit cards and other payment cards.
- The microcontroller chip on the card performs the processing and manipulating functions in the chips memory.
- Some organizations use smart cards for the authentication purpose.

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.
