Consider the following Go code block: var names = []string{“Alex”, “Bob”, “Chris”}for _, s := range names{ fmt.Printf(“%s,”, s) /* note: no space after the comma in the format string */} Write the output of the code block above exactly as it appears on screen: [output]

Which of the following statement declares two string variables named x and y and initializes them  to string literals “Hello” and “World” respectively?

Consider the following main function in a Go program which crashes (panic) eventually: func main(){    fmt.Println(“Start”)   defer fmt.Println(“Deferred call”)   panic(“Crashed”)} The deferred call in the main function will still be executed when this program is run.

Complete the following Go code block so that it declares grades as a map that maps student names to their grades and print out all student names and their grades (DON’T type unnecessary spaces in your answers):   grades := [maptype]{“Alex”: 93.2, “Bob”: 64.1, “Chris”: 70.5}   for [namegrade] := [range] grades {       fmt.Printf(“%s has a grade of %0.1f%%\n”, name, grade)    } Expected output: Alex has a grade of 93.2% Bob has a grade of 64.1% Chris has a grade of 70.5%

Given the following declaration: var s string = “GoLang” Match each fmt.Println() statement with its output. Recall that the ASCII code of character ‘G’ is 71, and the ASCII code of character ‘o’ is 111.

Define a Go’s struct type named BinaryTree that represents a binary tree. This struct must have three fields: one field of type int that represents the value at the root of the tree,  one field is a pointer pointing to the left subtree which is also of type BinaryTree one field is a pointer pointing to the right subtree which is also of type BinaryTree

The following Go code block will cause a panic: func main(){  var f func(string) int  fmt.Println(f(“test”))} 

What is the output of the following Go code block, assuming it is in the program that imports the fmt package: var x int = 20if  x := 10;  x < 11 {   fmt.Println("Value of x inside the if statement:", x)}fmt.Println("Value of x outside the if statement:", x)

Given the following Go code block: func test(n int, s string) int { return n*len(s)} What is the type of the variable t on the left-hand of the following statement? t := test

Preemptive scheduling is typically used with interactive operating systems. Match these classic scheduling algorithms: Shortest Remaining Time First, Round Robin, Preemptive Priority, and Compatible Time-Sharing System with their definitions.
