Sample Solution:

Swift Code:

func value_diff(nums: [Int]) -> Int {
    var min_num = nums[0]
    var max_num = nums[0]
    
    for x in 0..<nums.count 
    {
        min_num = min(nums[x], min_num)
        max_num = max(nums[x], max_num)
    }
    
    return max_num - min_num
}

print(value_diff(nums: [-5, -3, -7, 0]))
print(value_diff(nums: [8, 2, 14, 24]))  
print(value_diff(nums: [1, 0, 6, 3]))

Sample Output:

7
22
6
