Given the following function signature: func calculate(x int) int Assume that function calculate has different execution times for different arguments, that is, the time taken by the call calculate(x) is different from the time taken by the call calculate(y) as long as x is not equal y. Select the definition for variable ch in the following function definition so that when function test returns, there will be no leaked goroutines.  func test() {    ch := [makechan]    go func() { ch

Given the following Go code fragment: type Point struct {    X, Y float64} Write a code fragment that makes the Point struct implement  the built-in interface fmt.Stringer, assuming that the standard package fmt has been imported in the same package containing the given code fragment and your code fragment. The implementation must be done so that when calling fmt.Println to print an instance of Point, it will be printed in the following format: (X, Y)
