Chapter 1.4, Problem 23STE
Program Plan Intro
- A fault in a program denotes a bug and process of elimination of bugs is termed as debugging.
- A bug denotes an error, failure or fault in a program that may generate improper result.
- The process of fixing bugs is termed as debugging.
- Some of computer systems are able to deter, detect or auto correct different computer bugs during operations.
- The bugs arise from errors made in source code of program.
- The bugs can cause program to freeze computer in terms of processing.
Types of program errors:
- The three main types of program error includes:
- Syntax errors:
- The compiler catches certain mistakes and denotes an error message.
- It denotes violation of syntax of programming language.
- The compiler issues an error message if syntax is been violated.
- The compiler sometimes raises a warning message while any unusual programming practices.
- Run-time errors:
- It denotes type of error that system detects when a program is run.
- The system may detect certain run-time errors and displays appropriate error message.
- It may be an issue with numeric calculations.
- Logic error:
- It denotes a mistake in underlying
algorithm . - It may be an issue while translation of algorithm to program code.
- It denotes that there is no error in syntax while the result obtained is not as expected by user.
- These types of errors could be corrected by careful examination of algorithm and translation.
- It denotes a mistake in underlying
- Syntax errors:

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.
