Короче, кодиварс этот шляпа полная... )) Распиареный капец как, а по факту багов куча. 3задачки решил на Интеладжи, все четко, но кодиварс каждый раз меня тычет носом в какие то ошибки))) Я думал реально, что то дельное, а по факту пустышка, хотя начало было интрегующее

The last 3 pairs aren't consecutive perfect squares. Not a kata issue.

The exercise should mention what is the correct answer if there are multiple numbers satisfying the condition.

For input 27567, all of (13784**2, 13783**2), (4596**2, 4593**2), (1536**2, 1527**2), (524**2, 497**2)

My solution was one of the "3 variations" of someone else's solution, but it was actually out of only 2 variations. Has anybody else had the same problem?

passed in 12.140 seconds.. :)

Very nice!)

Thanks for pointing out the little error with the tests.
But your solution was actually wrong.

There appears to be an issue with tests on C# translation.

Expected: "-1795367280--1795467271"
But was: "2499600016-2499500025"

The input number was 99991 and my result was the same as the one provided in sample test. Seems like an issue with integer rollover.

I laghed on my slef alot when I solved it
let's say it's a funny challenge
Good One thanks!

Approved by someone ~~
