findKeithNumbers

Language/Type: C++ vector collections STL
Author: Keith Schwarz (on 07/06)

Write a function named findKeithNumbers that accepts minimum and maximum integers as parameters and prints all of the "Keith numbers in that range (inclusive) in the format shown below. See previous program isKeithNumber to learn the definition of a "Keith number." If the given range contains no Keith numbers, print no output. For example, the call of findKeithNumbers(47, 742); would print the following output:

47: {4, 7, 11, 18, 29, 47}
61: {6, 1, 7, 8, 15, 23, 38, 61}
75: {7, 5, 12, 17, 29, 46, 75}
197: {1, 9, 7, 17, 33, 57, 107, 197}
742: {7, 4, 2, 13, 19, 34, 66, 119, 219, 404, 742}

You may assume that a << output operator exists to print a vector in the format {10, 20, 30}.
