THREENUMBERS - nth number

no tags 

Given two numbers a and b, you have to find n-th number which is divisible by a or b.


First line contains an integer T (<= 100000), denoting number of test cases.

Second line contains 3 positive integers a, b and n. (a, b <= 10000, n <= 1000000000)


Print n-th number in a new line.

nice problem.

No need of binary search. Simple logic, AC in first go.

incorrect testCases... thanks @wisfaq for figuring it out.

Kudos to wisfaq for figuring out that the missing testcase requires reprinting the last result. Completely lame from psetter to leave something like this for solvers to handle. -1

Binary Search :-)

Some input files seem to be broken which will cause Fast I/O yielding TLE.
Use scanf for input.

very good problem :-)

Nice, I learned how to handle exceptions in Python

@wisfaq: Thanks for usefull hint!

@David (and others having problems with NZEC)
One of the ways to overcome those problems is to use error handling.
Something like:
__read a,b,n
__get answer(a,b,n)
__store answer
__print answer
_print stored (previous) answer.
That's the way I got AC with Python
