Yet another coding challenge (#6)

Question

Look at my answer for explanation.

Your program should either:
a) Have the user enter a number n and print the first n numbers of the look-and-say sequence
b) Have the user enter a number n and print the next number in the look-and-say sequence (for example, input = 8482739 would generate 18141812171319)
c) Have the user enter 2 numbers n and m and generate the first m numbers of a look-and-say sequence starting with n (for example: n = 3, m = 5 would be 3, 13, 1113, 3113, 132113 etc)

Answer 1

The look-and-say sequence defines as follows:

Start with 1.
Speak "one 1" (11)
Speak "two 1's" (21)
Speak "one 2, one 1" (1211)
Speak "one 1, one 2, two 1" (111221)
etc.

Answer 3

@Tobi nice code, but changing the number to something only a bit higher (I just tried 25) exceeds the time limit... can you make it faster?

@Jafca nice code, works perfectly!

Answer 4

Yay, a nontrivial use of reduce:
