CANTON - Count on Cantor

no tags 

One of the famous proofs of modern mathematics is Georg Cantor's demonstration that the set of rational numbers is enumerable. The proof works by using an explicit enumeration of rational numbers as shown in the diagram below.

1/1 1/2 1/3 1/4 1/5 ...
2/1 2/2 2/3 2/4
3/1 3/2 3/3
4/1 4/2
5/1

In the above diagram, the first term is 1/1, the second term is 1/2, the third term is 2/1, the fourth term is 3/1, the fifth term is 2/2, and so on.

Input

The input starts with a line containing a single integer t <= 20, the number of test cases. t test cases follow.

Then, it contains a single number per line.

Output

You are to write a program that will read a list of numbers in the range from 1 to 10^7 and will print for each number the corresponding term in Cantor's enumeration as given below.

Example

Input:
3
3
14
7

Output:
TERM 3 IS 2/1
TERM 14 IS 2/4
TERM 7 IS 1/4

This is actually a pretty decent question. Great constraints. Won't allow brute force preprocessing. You'll have to figure the (easy) pattern

Perfect example for Logic based problems!!!! Learnt a lot....

It might seem a bit typical at first, but if u get the pattern it is damn easy

Observe the series carefully..

AC in 1st attempt. My 25th problem .

Need to know a couple of equations on triangular numbers. The rest is just conceptualising how the terms move along the diagonal.

Yeah

AC in 1st go :) My 75th on spoj :)

How is third term not 1/3
