Challenge 19: Slice Operations

Problem Statement

Write functions to perform common operations on slices (Go's dynamic arrays). You'll implement the following functions:

1. FindMax - Find the maximum value in a slice of integers.
2. RemoveDuplicates - Remove duplicate values from a slice while preserving order.
3. ReverseSlice - Reverse the order of elements in a slice.
4. FilterEven - Create a new slice containing only even numbers from the original slice.

Function Signatures

func FindMax(numbers []int) int
func RemoveDuplicates(numbers []int) []int
func ReverseSlice(slice []int) []int
func FilterEven(numbers []int) []int

Input Format

• For all functions, a slice of integers.

Output Format

• FindMax - A single integer representing the maximum value.
• RemoveDuplicates - A slice of integers with duplicates removed.
• ReverseSlice - A slice of integers in reverse order.
• FilterEven - A slice containing only even integers.

Requirements

1. FindMax should return the maximum value from the slice. If the slice is empty, return 0.
2. RemoveDuplicates should preserve the original order of elements while removing duplicates.
3. ReverseSlice should create a new slice with elements in reverse order.
4. FilterEven should return a new slice containing only even numbers.

Sample Input and Output

Sample Input 1

FindMax([]int{3, 1, 4, 1, 5, 9, 2, 6})

Sample Output 1

9

Sample Input 2

RemoveDuplicates([]int{3, 1, 4, 1, 5, 9, 2, 6})

Sample Output 2

[3 1 4 5 9 2 6]

Sample Input 3

ReverseSlice([]int{1, 2, 3, 4, 5})

Sample Output 3

[5 4 3 2 1]

Sample Input 4

FilterEven([]int{1, 2, 3, 4, 5, 6})

Sample Output 4

[2 4 6]
