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 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.
Find the n’th term in Look-and-say (Or Count and Say) Sequence.
In mathematics, the look-and-say sequence is the sequence of integers beginning as follows
Replace a[i] by last here (you may not want to add anything in the first round). After the loop you have to add the last value of the counter together with the last character again (this was not yet done), i.e. add another result = result+str(k)+last after the loop. In total it looks like.
Trouble is I'm not sure if it's totally correct. It's quite short though. I was just hoping someone could look it over and see if it is a valid proof. Thank you!
A005150. Look and Say sequence: describe the previous term! (method A - initial term is 1). (Formerly M4780).
Look-and-Say sequences. A look-and-say sequence is a sequence of integers, expressed in decimal notation, where each sucessive term is generated by describing the previous one.
For sure you know what is the look & say sequence. See these A, B & C, references.
