Test instructions: give you n integers, to find the square root of the n number and whether it is an integer;

Problem-solving ideas: If the problem of each count to him, the inevitable time, may also be super-precision, so the ingenious method is to determine whether these integers are completely square number, if there is a not, then their square root and certainly not an integer.

AC Code:

#include <cstdio>#include<cmath>#include<cstring>#include<algorithm>#include<iostream>using namespacestd;int  is(intx) {  inty=sqrt (x); if(y*y==x)return 0; return 1;}intMain () {intN; while(SCANF ("%d", &n)! =EOF) {  intf=1;  for(intI=0; i<n;i++)  {   intx; scanf ("%d",&x); if( is(x)) f=0; }  if(f) Puts ("Yes"); ElsePuts"No"); } return 0;}
