Variable Sized Arrays

Consider an n-element array, a, where each index i in the array contains a reference to an array of k[i] integers (where the value of k[i] varies from array to array).

Given a, you must answer q queries. Each query is in the format i, j, where i denotes an index in array a and k denotes an index in the array located at a[i]. For each query, find and print the value of element j in the array at location a[i] on a new line.
