In which of the following cases does recursion occur?

Question

BlackTom AI · Accepted Answer

The question asks: In which of the following cases does recursion occur?

Option 1: 'When a method calls itself' — This matches the standard definition of recursion in programming, where a function or method invokes itself to solve a smaller or simpler instance of the same problem.

Option 2: 'When an ordered index number is assigned to each character in a string' — This describes indexing or enumeration, not recursion. Assigning indices is a procedural step for access, not a self-referential call.

Option 3: 'When human-readable terms are converted to computer-readable terms' — This refers to encoding or compilation/translation (lexical analysis, encoding, or compilation) rather than recursion, which is about repeated self-invocation.

Option 4: 'When an integer variable transforms into a double variable' — This is a type conversion or casting operation, not a recursive process; it doesn’t involve a function invoking itself.

In summary, recursion is exemplified by a method calling itself, while the other options describe different programming concepts (indexing, translation/compilation, and type conversion) that do not constitute recursion.
