It will be good - if we not insert in the placeholder of the while cycle something - it will be an invisible 1.
Compare please two programs:
We need to have infinity cycle with one or more exits. An exit in the top of this cycles - we have a while cycle, an exit in the below of this cycle - we have a repeat cycle etc
PS
The task
Three fishermen lay down to sleep, not having counted or divided their catch. In the night, one of them woke up, and (not quite trusting the others) decided to divide the pile of fish and take his share. But the number of fish wasn't visible by three. However, he found he could throw one fish away, then take exactly a third. This he did (noting, in the true spirit of fairness, that an even number of fish was left for his comrades) and went back to sleep. Later, the second and third fishermen woke in turn, and each went through the same process. The question is, what is the MINIMUM number of fish in the catch that fulfils these conditions?
