1001. Reverse Root

Time limit: 2.0 second
Memory limit: 64 MB

The problem is so easy, that the authors were lazy to write a statement for it!

Input

The input stream contains a set of integer numbers A_i (0 ≤ A_i ≤ 10¹⁸). The numbers are separated by any number of spaces and line breaks. A size of the input stream does not exceed 256 KB.

Output

For each number A_i from the last one till the first one you should output its square root. Each square root should be printed in a separate line with at least four digits after decimal point.

简单的一道题，注意下输入就可以了，还有后面要倒序输出平方根，可惜没看清题，WA了几次。。。。

贴下代码：

By LFENG

#include<stdio.h> #include<math.h> double a[1000000]; int main() {     int i=0,j;     while(scanf("%lf",&a[i])!=EOF)         i++;     for(j=i-1;j>=0;j--)         printf("%.4lf\n",sqrt(a[j]));     return 0; }
