CANTON - Count on Cantor |
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 107 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

getting annoyed what the hell my answers are correct to all input including 10^7 but still getting WA. got the case where i was mistaken it's in zigzag manner Last edit: 2013-12-17 19:17:39 |

I was so angry at myself for struggling with this one. After AC I can tell it was worth it. |

cool number magic.. takes O(1) time to find out the N'th term. just have fun with arithmetic series & you'll eventually discover something fun ;) |

(chandu) it can continues upto infinity (whole matrix) no problem u have to find the term (http://en.wikipedia.org/wiki/Cantor_pairing_function#Cantor_pairing_function) Last edit: 2013-05-16 04:55:03 |

don't forget to print 'TERM' and 'IS' in capital letters. |

i did everything correct and it also works in ideone and codeblocks compilers but when i submit it shows error |

Nice one! I chose the analytical way and solved it on paper actually. :) This math doesn't even require any algorithms... |
