Two Interview Questions
February 18, 2014
It’s been a while since we had any interview questions. We have two today, since they are so simple:
1) Given a number n, find the smallest 3-digit number such that the product of its digits is equal to n. For example, given n = 100, the solution is 455.
2) Given two arrays, one with n items and one with n+2 items including the same items as the array with n items plus two additional items, find the two additional items. Assume none of the items are duplicates.
Your task is to write solutions to the two interview questions given above. When you are finished, you are welcome to read or run a suggested solution, or to post your own solution or discuss the exercise in the comments below.
