Last update on December 21 2024 10:28:45 (UTC/GMT +8 hours)

Write a Swift program to test if a given array of integers contains two 5's next to each other, or there are two 5's separated by one element.

Example: {5, 5, 1}, {5, 1, 5}

Sample Solution:

Swift Code:

func num55(array_nums: [Int]) -> Bool {
    for x in 0..<array_nums.count-1 
       {
        if (array_nums[x] == 5 && array_nums[x+1] == 5) || (array_nums[x] == 5 && array_nums[x+2] == 5) 
        {
            return true
        }
    }
      return false
}
print(num55(array_nums: [1, 5, 5]))
print(num55(array_nums: [1, 5, 1, 5]))
print(num55(array_nums: [1, 5, 1, 1, 5]))

Sample Output:

true
true
false
