Java Coding Interview: Zip and Pad Lists

Solving Java interview coding question

Question: Zip and Pad Lists

Write a function named zipAndPad() that takes two lists of potentially different lengths as input. The function should return a list of pairs (as lists), where each pair consists of one element from each input list. If one list is longer than the other, pad the missing elements with an empty string.

Examples:

cust_id = { 1, 2, 3 };
cust_name = { "sam", "den", "lenny" };
customers = { {1,"sam"}, {2,"den"}, {3, "lenny"} };
