In mathematics, the look-and-say sequence is the sequence of integers beginning as follows: 1, 11, 21, 1211, 111221, 312211, 13112221, 1113213211, . . .

To generate a member of the sequence from the previous member, read off the digits of the previous member, counting the number of digits in groups of the same digit. For example: 1 is read off as one 1 or 11 11 is read off as two 1s or 21 21 is read off as one 2, then one 1 or 1211 1211 is read off as one 1, one 2, then two 1s or 111221 111221 is read off as three 1s, two 2s, then one 1 or 312211

Write the function look say() that takes an integer giving which term of the look-and-say sequence we want, starting from 0, and returns a string containing that term. Term #0 is 1, term #1 is 11, term #2 is 21, and so on. Your function must return the correct string for any non-negative integer argument. No matter how long the numbers become, the only digits that will appear are 1, 2 and 3.
