Description

Write a program to calculate integer square roots.

Input

The input is read from a text file named squint.in. Its only line consists of an integer 0 < = n < 2^63 .

Output

Its only line consists of the smallest nonnegative integer q such that q^2 >= n .

Sample Input

122333444455555

Sample Output

11060446

HINT

sqrt(122333444455555)=11060445.038765619 .

 题解:题目说的很明白了——跟我念square root——平方根= =

然后就没别的了,注意设求出的平方根为r,则\({r}^{2} >= N\)= =为此又逗比了几次= =
