Speed of Sound
The following table shows the approximate speed of sound in air, water, and steel.
Create an application that displays a set of radio buttons allowing the user to select air, water, or steel. Provide a text box to let the user enter the distance a sound wave will travel in the selected medium. Then, when the user clicks a button, the
Format the output to two decimal places.
Input validation: Do not accept distances less than 0. Always check for nonnumeric data.
Use the following test data to determine if the application is calculating properly:

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.
