Extra数青蛙

有一天，Extra来到一个青蛙王国，看到一群青蛙在跳水，于是他感到很神奇，就在一旁数青蛙：“一只青蛙一张嘴，两只眼睛四条腿，扑通一声跳下水……”不过Extra已经不在是幼儿园的小朋友了，他会使用英文来数。他还能从第K只青蛙数到第S只青蛙

第一行输入N，表示有几组数据

每一组包括两个大于0的整数K，S，表示从第K只青蛙数到第S只青蛙

按以下格式输出

1 frog has 1 mouth, 2 eyes and 4 legs, jumps into the water with a splash.

2 frogs have 2 mouths, 4 eyes and 8 legs, jump into the water with splash splash.
