EIGHTS - Triple Fat Ladies

Pattern Matchers have been designed for various sorts of patterns. Mr. HKP likes to observe patterns in numbers. After completing his extensive research on the squares of numbers, he has moved on to cubes. Now he wants to know all numbers whose cube ends in 888.

Given a number k, help Mr. HKP find the kth number (indexed from 1) whose cube ends in 888.


The first line of the input contains an integer t, the number of test cases. t test cases follow.

Each test case consists of a single line containing a single integer k (1 <= k <= 2000000000000).


For each test case, output a single integer which denotes the kth number whose cube ends in 888. The result will be less than 263.

Any ideas how one can find the pattern easely without spoj toolkit? Thx to toolkit got AC

Haha 3 lines of code....

Don't give up :) I struggled with this many hours and at times I thought too complexly.

In c++ use boost multiprecision 5-7 line code !!

should have given 2 test cases

very bad explanation :(

Got it!! But I don't see any good in this pattern!! What is relation b/w 888 and the logic?? How we get logic without seeing 1st few test cases in spoj tool kit?? What is the relation b/w Cubes or 888 and 250??

Simran Saha: 2017-05-22 06:26:15

Required more test cases....at least one more :P

Very easy! Lol!! Good Pattern, though!
