List of lectures for the course Go, 2 quest level on JavaRush

The IT Industry and You
Go SELF
2 level,0 lecture
In this lecture, you will learn how the information revolution changed the world, why IT companies became the largest and most valuable, what opportunities a career in IT opens up, and why now is the best time to become a programmer. Examples, numbers, and inspiring facts!
Open
Integers in Go: int, arithmetic, and precedence
Go SELF
2 level,1 lecture
In this lecture, you will learn the basic integer type int in Go: how the arithmetic operators +, -, *, /, % work, why dividing int by int discards the fractional part, how operator precedence is arranged, and what typical mistakes beginners make most often. At the end, there is a mini-project with “pizza” and progress calculation.
Open
Strings: type string, concatenation, len
Go SELF
2 level,2 lecture
In this lecture, you will learn the basics of working with strings in Go: what the string type is, how to create string literals and variables (using var and :=), how to join strings with the + operator, how to print text using fmt.Print and fmt.Println, and also how len(s) works and why a string length in bytes is not always equal to the number of “visible” characters (UTF-8).
Open
Input in Go: fmt.Scan and fmt.Fscan
Go SELF
2 level,3 lecture
In this lecture, you will learn how to read input in Go using fmt.Scan and fmt.Fscan: how input is split into tokens, why you need & in front of variables, what the return values count and err mean, and how regular errors differ from panic. At the end, you will find a list of common mistakes and quick explanations of how to avoid them.
Open
String ↔ int conversions in Go: Atoi and Itoa
Go SELF
2 level,4 lecture
In this lecture, you will learn explicit conversions between the string and int types in Go using the strconv package. You will learn how to use strconv.Atoi (parsing a string into a number) and strconv.Itoa (converting a number to a string), understand the role of error/ nil, and see common mistakes that cause parsing to “break”.
Open
Template: read → parse → compute → print
Go SELF
2 level,5 lecture
In this lecture, you will break down a universal template for solving problems with standard input/output in Go: read → parse → compute → print. You will learn to separate input reading from parsing, computations, and output so that your code is predictable, readable, and easier to debug.
Open
JavaRush platform: how learning is structured
Go SELF
2 level,6 lecture
Get to know how the JavaRush platform works: how courses and the University are organized, what quests and modules are, how the system of levels, lectures, and tasks works, why you need “Black Matter”, where to get help, and how to learn from mobile. This lecture is your guide to JavaRush capabilities!
