Functions That Accept Other Functions as Parameters
Explore how in Go programming, functions can accept other functions as parameters. Understand the use of sort.Slice and sort.SliceIsSorted to implement custom sorting by passing functions that define ordering rules. Learn to write and use anonymous and regular functions for flexible and efficient sorting mechanisms.

Functions can accept other functions as parameters. The best example of a function that accepts another function as an argument can be found in the sort package. We can provide the sort.Slice() function with another function as an argument that specifies the way sorting is implemented.
Signature of sort.Slice()
The signature of sort.Slice() is func Slice(slice interface{}, less func(i, j int) bool). This means the following:
