Given two arrays a and b. Given q queries each having a positive integer i denoting an index of the array a. For each query, your task is to find all the elements less than or equal to q_{i} in the array b.
Example 1:
Input:
N=6
a[] = {1, 2, 3, 4, 7, 9}
b[] = {0, 1, 2, 1, 1, 4} 
Query 1 -> 5
Query 2 -> 4
Output : 6
         6
Explanation: For 1^{st} query, the given index is 5,
             A[5] is 9 and in B all the elements 
             are smaller than 9.
             For 2^{nd} query, the given index is 4, 
             A[4] is 7 and in B all the elements 
             are smaller than 7.   
Your Task:
Since, this is a function problem. You don't need to take any input, as it is already accomplished by the driver code. You just need to complete the function find() that takes array a , array b, array q as parameters and returns an array that contains the answer to the corresponding queries.
