How to solve the Codewars's Find the next perfect square!
Today I try to solve the algorithm problem of codewars.
Description
You might know some pretty large perfect squares. But what about the NEXT one?
Complete the findNextSquare method that finds the next integral perfect square after the one passed as a parameter. Recall that an integral perfect square is an integer n such that sqrt(n) is also an integer.
If the parameter is itself not a perfect square, than 1 should be returned. You may assume the parameter is positive.
Examples

findNextSquare(121) > 144

findNextSquare(625) > 676

findNextSquare(114) > 1
Code
not a perfect square : sq != Math.floor(Math.sqrt(sq)) * Math.floor(Math.sqrt(sq)).
next square : Math.sqrt(sq) + 1 * Math.sqrt(sq) + 1.
Math.round() : returns the closest long or int number.
public class NumberFun {
public static long findNextSquare(long sq) {
# Codewars COC 정책으로 인하여 코드 제거
return Math.round(tmp*tmp);
}
}
