Relax! It's just a game#1334
You: What's the score? Did I miss much?
Me: It's - for elAhli and the second half just started. The first half was quite boring.
You: Who scored first? elAhli or ezZamalek?
Me: What difference does it make?
You: Big difference! I can predict the outcome of the match if I knew the order in which the goals were scored in the first half.
Me: What do you mean?
You: It's 2-1 for elAhli, right? One of three things could have happened: elAhli scored two goals, then ezZamalek scored; or, elAhli scored its first goal, then ezZamalek, then elAhli again; or, ezZamalek scored first, then elAhli scored its two goals.
Me: So?!! I still don't understand what difference that makes. It's still 2-1 for elAhli! Why don't you just relax and let us continue watching the game in peace.
You: You don't understand!! I believe the probability of who'll win depends on the order in which goals were scored. Now I have to predict the result for 3 possibilities.
Me: And what if the score was 3-2? What would you have done then?
You: I'd have to consider 5 different possibilities. No?
Me: Of course not! The number of possibilities isn't always equal to the sum.
You: Can you tell me when it will be equal to the sum?
Me: You're a programmer, why don't you write a program that counts the number of possibilities and compares it to the sum?
You: I don't have time, I want to watch the match. Besides, I have nine other problems to worry about.
Me: I'll give you a hint. The number of possibilities will be equal to the sum only if one of the teams scored a certain number of goals.
Your program will be tested on one or more test cases. Each test case specifies two natural numbers and (separated by one or more spaces), representing the score of the first half. No team will be able to score more than goals. The last line of the input file contains two (this is not part of the test cases).
For each test case where the number of possibilities is equal to the sum, print:
A+B=C
Where and are as above, and is their sum. If the number of possibilities is not equal to the sum, replace the = sign with != (without the quotes).
