The square root floor of a nonnegative integer n is the largest integer i such that the square of i is less than or equal to n. Write a program that reads a sequence of integers and prints the square root floor of each integer (on a separate line). You may assume that each integer is between 1 and 1000000000. Your program must stop if it reads something other than an integer or encounters the end of input. For example, if the user types 1 99 100 101 x 37, your program will display 1 9 10 10 (on four lines).
