ALONE - FOREVER ALONE
IAR and FA numbers
Numbers can be classified as IAR numbers and FA numbers.
Numbers in which all digits are equal to either adjacent digit are called In-A-Relationship numbers. For example: 11, 22, 111, 9922888 and 777788822 are IAR numbers.
Numbers featuring lonely digits are called Forever-Alone (FA) numbers. For example: in 22122 digit 1 is alone and in 123 all digits are alone.
Given K, your task is to find the Kth In-A-Relationship (IAR) number.
Input
The first line contains number of test cases T ( T <= 50 )
Then T test cases follow.
Each line contains one integer K (1 <= K <= 5*10^6)
Output
For each test case, print the Kth IAR number.
Sample Input
5
1
2
3
10
12
Sample output
11
22
33
111
333
