Part III: The Look-and-Say Sequence (5 points) 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: o 1 is read off as "one 1" or 11 11 is read off as "two ls" 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 ls" or 111221 111221 is read off as "three ls, 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 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 Examples: Function Call Return Value look-say (3) 1211' look-say (8) 31131211131221' look-say (12) 1321 132 1321 1121312 21 1231131 1222113 11 1221 131221 Note that the quotation marks displayed in the return values are there to emphasize that the return values are strings. You should not add quotation marks to your return values
