import Foundation

public extension Array {
	func slice(count: Int) -> [some Collection] {
		let n = self.count / count	// quotient
		let i = n * count 			// index
		let r = self.count % count	// remainder
		let slices = (0..<n).map { $0 * count }.map { self[$0 ..< $0 + count] }
		return (r > 0) ? slices + [self[i..<i + r]] : slices
	}
