Expert Solution & Answer
Chapter 3, Problem 1MQ1
Explanation of Solution
Variable:
- A variable is a computer memory location that stores the programmers’ data temporarily.
- A data stored in a variable is processed faster than the data stored in the property of a control.
- The contents of the variable can be changed during run time.
- The user provided data item will be stored in a variable and it will be used in a calculation during run time.
Syntax:
{Dim | Private | Static} variableName As dataType [=initialValue]
Example:
Dim decTime As Decimal
Here, the decTime is declared as a decimal variable and it is automatically initialized by the value 0.
Therefore, the statement user-provided item that will be used in a calculation should be stored in a variable is correct.
Hence, the given statement is “True”.

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.
