Look-and-say sequence - Rosetta Code


The Look and say sequence is a recursively defined sequence of numbers studied most notably by John Conway. Sequence Definition. Take a decimal number. Look at the number, visually grouping consecutive runs of the same digit.

Look-and-say sequence - Wikipedia, the free encyclopedia


In mathematics, the look-and-say sequence is the sequence of integers beginning as follows: 1, 11, 21, 1211, 111221, 312211, 13112221, 1113213211, ... (sequence A005150 in OEIS). To generate a member of the sequence from the previous member, read off the digits of the previous member...

The look and say sequence is a basic form of run length encoding. The sequence starts with the number 1 and each additional number encodes the number of digits that are repeated before each digit sequence.

As with the regular look-and-say sequence, the way we will attack these sequences is by constructing a “periodic table” of elementary non-interacting subsequences that all terms in the
