Need help in Intersting Math Problem (SWERC — 2019-20)

Revision en2, by mujtaba1747, 2020-05-05 21:20:58

Hi, I was trying to solve this 102501H - Pseudo-Random Number Generator. I tried to find a pattern but couldn't due to the large constraints. The editorial claims that we need to find the Period of the sequence but I am unable to do so. Any help / suggestions are welcome.
