Boom numbers are numbers consisting only of digits 2 and 3. Given an integer k, display the k-th Boom number.
The first line of input contains a single integer T denoting the number of test cases. Then T test cases follow. Each test case consist of one line. The first line of each test case consists of an integer K.
Corresponding to each test case, in a new line, print the Kth boom number.
1 ≤ T ≤ 100
1 ≤ K ≤ 1000000
