Motivation

Starting from December 8, 2020, Apple has required new apps and app updates to include App privacy details on the App Store. App owners have to go through every pod and all its dependency's readmes or if nothing is revealed then reach out to pod creators to just figure out what information the pod collects. The current process is not transparent nor easy.

Proposal

class Solution {
   func removeKdigits(_ num: String, _ k: Int) -> String {
        var drops = k
        var maxStack: [Character] = []
       
       for digit in num {
           // only if there is something bigger in the stack to drop...
           while drops > 0 && !maxStack.isEmpty && maxStack.last! > digit {
               maxStack.popLast()
               drops -= 1

    var remaining : [String: Int] = ["(": 0, "[": 0, "{": 0]

        let opens = ["[", "(", "{"]
