The following conversation is overheard between Alice and Bob:Alice: I don’t know my number.Bob: I don’t know my number.Alice: I don’t know my number.Bob: I don’t know my number.They say this to each other 200 times. And then we overhear them say: Alice: I know my number! Bob: I know my number too!Can you explain the conversation and figure out the numbers x and y.
