Can Jump

Given an array of non-negative integers representing the maximum number of steps you can take forward from each position, implement the function CanJump() which takes a []uint as input and returns a boolean value to determine if it's possible to reach the last index starting from the first index based on these maximum steps. The function should return true if it's possible to reach and stay at the last index without stepping out of the array and false otherwise.

Note: Remember, if the input has only one element, that is the last position in the array so the function will return true but if the array is empty it returns false.

Usage

Here is a possible program to test your function:

package main

import (
	"fmt"
	"piscine"
)

func main() {
	input1 := []uint{2, 3, 1, 1, 4}
	fmt.Println(piscine.CanJump(input1))

	input2 := []uint{3, 2, 1, 0, 4}
	fmt.Println(piscine.CanJump(input2))

	input3 := []uint{0}
	fmt.Println(piscine.CanJump(input3))
}

And its output :

$ go run .
true
false
true
$
