405388: GYM101933 B Baby Bites

Arild just turned $$$1$$$ year old, and is currently learning how to count. His favorite thing to count is how many mouthfuls he has in a meal: every time he gets a bite, he will count it by saying the number out loud.

Unfortunately, talking while having a mouthful sometimes causes Arild to mumble incomprehensibly, making it hard to know how far he has counted. Sometimes you even suspect he loses his count! You decide to write a program to determine whether Arild's counting makes sense or not.

The first line of input contains an integer $$$n$$$ ($$$1 \le n \le 1\,000$$$), the number of bites Arild receives. Then second line contains $$$n$$$ space-separated words spoken by Arild, the $$$i$$$'th of which is either a non-negative integer $$$a_i$$$ ($$$0 \le a_i \le 10\,000$$$) or the string "mumble".

If Arild's counting might make sense, print the string "makes sense". Otherwise, print the string "something is fishy".
