Most Frequent Element In Array Swift With Code Examples

In this tutorial, we’ll attempt to discover the answer to Most Frequent Element In Array Swift by programming. The following code illustrates this.

func mostFrequent(array: [Int]) -> (worth: Int, depend: Int)? {
    var counts = [Int: Int]()

    array.forEach { counts[$0] = (counts[$0] ?? 0) + 1 }

    if let (worth, depend) = counts.max(by: {$0.1 < $1.1}) {
        return (worth, depend)
    }

    // array was empty
    return nil
}

if let outcome = mostFrequent(array: [1, 3, 2, 1, 1, 4, 5]) {
    print("(outcome.worth) happens (outcome.depend) instances")    
}

The Most Frequent Element In Array Swift concern was overcome by using a wide range of completely different examples.

How do you discover probably the most frequent in an array?

Solution Steps

  • We first kind the array utilizing some environment friendly O(nlogn) sorting algorithm like merge kind, heap kind, or quicksort.

  • Now we scan sorted array utilizing a loop until i < n.

How do you discover probably the most frequent worth in an array in NumPy?

Steps to search out probably the most frequency worth in a NumPy array: Create a NumPy array.
