statement of problem is not logistical
Послано Alias (Alexander Prudaev) 25 авг 2007 17:03
i write program which have wa#1

"But it appeared that among those problems there were some,
which have the analogous solutions."

for me it's very difficult to understand such situation:

solution of problem A is "analogous" to solution of problem B
and solution of problem B is "analogous" to solution of problem C
BUT solution of problem A is NOT "analogous" to solution of problem C

in other words relation "analogous" is not transitive

this fact must be clarified in the problem statement
