In approximate string matching, the objective is to find matches for short strings in many longer texts, in situations where a small number of differences is to be expected. The short strings could come from a dictionary, for instance. Here, one of the strings is typically short, while the other is arbitrarily long. This has a wide range of applications, for instance, spell checkers, correction systems for optical character recognition, and software to assist natural-language translation ba… WebApr 2, 2024 · It's important to understand that the value is on the right-hand side of the comparison can be converted to the type of the left-hand side value for comparison.
