What programming language to choose for school competitions?

Question

Programming languages

I've been programming in c# for 2 years, so I'm most comfortable with it. Familiar with C++. The matter is complicated by the fact that not all Olympiads accept c#.

Answer 1

Most of the Olympiads perform tasks on the pluses (speed of work + the ability to solve the problem in several ways), but you need to know it not at a superficial level if you want to become a prize-winner/winner.
Where C# is accepted, you can use it, because the more you know the tools for solving, the greater the chance to complete the task (I myself use Java / C ++).

Answer 2

easy tasks - python
international olympiad - c++14, rarely java
