Swift Array Programming: Exercise-15 with Solution

Write a Swift program to check if two given arrays of integers have 0 as their first element.

Pictorial Presentation:

Sample Solution:

Swift Code:

func start1(_ a: [Int], _ b: [Int]) -> Bool {
    var ctr = 0
    
    if a.first == 0
    {
        ctr += 1
    }
    
    if b.first == 0 
    {
        ctr += 1
    }
    
    if  ctr == 2
   {
        return true
   }
   else 
   {
        return false
    }
	
}

print(start1([0, 1, 2], [0, 1]))
print(start1([0, 1, 2], [1, 2]))
print(start1([0, 1], [0]))

Sample Output:

true
false
true
