What is the concept of well-conditioned problems in Numerical Analysis?

Well-conditioned problems in Numerical Analysis refer to mathematical problems that are stable and have a small sensitivity to changes in the input data or parameters. In other words, a well-conditioned problem is one where small changes in the input result in small changes in the output. This is desirable because it means that the numerical methods used to solve the problem will produce accurate and reliable results.
