issorted

Instructions

Write a function IsSorted that returns true if the slice of int is sorted, and that returns false otherwise.

The function passed in parameter returns a positive int if a(the first argument) is superior to b(the second argument), it returns 0 if they are equal and it returns a negative int otherwise.

To do your testing you have to write your own f function.

Expected function

func IsSorted(f func(a, b int) int, tab []int) int {
}

Usage

Here is a possible program to test your function (without f):

package main

import (
	"fmt"
	piscine ".."
)

func main() {
	tab1 := []int{0, 1, 2, 3, 4, 5}
	tab2 := []int{0, 2, 1, 3}

	result1 := piscine.IsSorted(f, tab1)
	result2 := piscine.IsSorted(f, tab2)

	fmt.Println(result1)
	fmt.Println(result2)
}

And its output :

student@ubuntu:~/piscine/test$ go build
student@ubuntu:~/piscine/test$ ./test
true
false
student@ubuntu:~/piscine/test$
