Look-and-Say Sequence

Generates the famous look-and-say sequence, also known as the Conway sequence. This tool iteratively expands a given starting number or string by describing the count of consecutive digits found in the previous output. For example, if the input is 1, the tool outputs 11 (one one). The next iteration describes 11 as two ones, resulting in 21. It continues this process, where each subsequent term is a literal description of the numeral patterns in the preceding term. Individuals studying number theory or recreational mathematics utilize this sequence generator to explore its unique mathematical properties and rapid growth rate. Students learning about combinatorial sequences can use it to visualize how simple descriptive rules lead to complex numerical outputs.
