坑！记得用float,用int直接WA。

   1:  #include<stdlib.h>

   2:  #include<stdio.h>

   3:  int main(){

   4:      int cases;

   5:      float a,b,c;

   6:      scanf("%d",&cases);

   7:      while(cases--){

   8:          scanf("%f %f %f",&a,&b,&c);

   9:          if(a+b>c&&a+c>b&&b+c>a)

  10:              printf("YES\n");

  11:          else

  12:              printf("NO\n");
