Can you name the main standard libraries included in the Golang standard distribution?

The standard library of Go includes many packages that cover essential programming tasks. Here are some of the key standard libraries:

• fmt — formatted input/output (printing, scanning).
• net/http — implementation of HTTP client and server.
• io and io/ioutil — working with input/output and files.
• os — interaction with the operating system (files, processes).
• strings — functions for working with strings.
• strconv — type conversion, for example, from string to number.
• time — working with date and time.
• math and math/rand — mathematical functions and random number generation.
• encoding/json — encoding and decoding JSON.
• sync — synchronization primitives (mutexes, waiting).
• context — managing the lifetime of operations and cancellation.

These libraries allow solving a wide range of tasks without installing third-party packages.
