Declaration
@warn_unqualified_access func min() -> UInt?
Return Value
The sequence’s minimum element. If the sequence has no elements, returns nil.
Discussion
This example finds the smallest value in an array of height measurements.
let heights = [67.5, 65.7, 64.3, 61.1, 58.5, 60.3, 64.9]
let lowestHeight = heights.min()
print(lowestHeight)
// Prints "Optional(58.5)"
Complexity: O(n), where n is the length of the sequence.
