Go

Go is a statically typed, compiled language designed for simplicity and performance. It is increasingly popular in backend and infrastructure roles and is commonly used at companies like Uber, Cloudflare, and Docker. Its syntax is minimal, and its concurrency model is distinctive, but for LeetCode purposes, what matters is its straightforward standard library and fast execution. Go does not have a built-in generic data structure library as rich as Java or C++, so you will sometimes need to implement things like heaps from scratch using the container/heap interface. It is a good choice if Go is your day-to-day language.
