To verify boundary values, you need to test the input values at the boundaries of valid ranges. This includes testing values at the lower and upper limits of the valid range, as well as just outside those limits. By testing these boundary values, you can ensure that the system behaves correctly and handles edge cases properly. It is important to also consider any special cases or exceptions that may exist at the boundaries. **

One can verify computationally by using algorithms and computer programs to check the accuracy and validity of a given solution or result. This can involve running simulations, performing calculations, or comparing outputs with known data or benchmarks. By using computational tools, one can efficiently and effectively verify the correctness of a solution without having to rely solely on manual or theoretical methods. **
