LintCode题解之判断是否为平方数之和
简单粗暴
public class Solution { /* * @param : the given number * @return: whether whether there're two integers */ public boolean checkSumOfSquareNumbers(int n) { int max = (int)Math.sqrt(n) + 1; for(int i=0; i<max; i++){ for(int j=0; j<max; j++){ if(i*i + j*j == n) return true; } } return false; } };
