Knowing multiple languages is beneficial, as some languages offer unique features or efficiencies suited for specific types of problems.

While it’s possible to excel in competitive programming with a single language, knowing multiple languages can provide strategic advantages. Each language has unique strengths: C++ is popular for its fast execution and extensive Standard Template Library (STL), Python excels in readability and has powerful libraries, while Java offers strong handling for complex objects and large numbers. Certain problems may benefit from specific features, such as Python’s arbitrary-precision integers or C++’s efficient STL. Being able to switch languages based on the contest rules or problem requirements adds versatility to a programmer’s skillset, giving them flexibility and enhancing their problem-solving toolkit. Learning additional languages can also deepen a programmer’s understanding of computational concepts and expand their approach to solving problems efficiently.
