CA 17 - Write a blog on "How a request originates from cllient and reaches the server ?"

FLOW OF SEARCHING FOR IP ADDRESS:


 USER(request) ---> DNS query initiation ---> Subresolver(local machine), Internal[DHCP,Cache] --->

Root  (.org,.com,.in) ---> TLD(Top Level Domain) ---> SLD(Secondary Level Domain) ---> 

Subdomain ---> IP


For example : www.Youtube.com is the website address to be searched

1.The Url request from client moves to the DNs

2.DNS request for the Ip address

3.Subreslover searches for the ip address in the cache if yes it gives the ip to DNS else it asks for the root 

4. The root knows the TLD and request to it and TLD request it to the SLD

5.If the ip address situated in the TLD OR SLD it completes the request and gives to the User or else move to the subdomain

6.Where the subdomain moves to the DNS server where it contains the ip address

7.The IP address get stored in the cache and moves to the url

  CA 09 - Move All Negative Elements to end Move all negative elements to end Difficulty:  Easy Accuracy:  56.24% Submissions:  174K+ Points:  2 Given an unsorted array  arr[ ]  having both negative and positive integers. The task is to place all negative elements at the end of the array without changing the order of positive elements and negative elements. Note :  Don't return any array, just in-place on the array. Examples: Input : arr[] = [1, -1, 3, 2, -7, -5, 11, 6 ] Output : [1, 3, 2, 11, 6, -1, -7, -5] Explanation: By doing operations we separated the integers without changing the order. Input : arr[] = [-5, 7, -3, -4, 9, 10, -1, 11] Output : [7, 9, 10, 11, -5, -3, -4, -1] MY CODE: class Solution: def segregateElements(self, arr): a = [] b = [] for i in arr: if i >= 0: a.append(i) else: b.append(i) temp = a + b fo...

  CA 06 - Find the Maximum and Minimum Element in the Array Min and Max in Array Input: arr[] = [1, 4, 3, 5, 8, 6] Output: [1, 8] Explanation: minimum and maximum elements of array are 1 and 8. Input: arr[] = [12, 3, 15, 7, 9] Output: [3, 15] Explanation: minimum and maximum element of array are 3 and 15. MY CODE: The min and max are the functions which shows the maximum and minimum element class Solution: class Solution: def getMinMax(self, arr): a = arr[0] # min b = arr[0] # max for c in range(1, len(arr)): d = arr[c] if d < a: a = d if d > b: b = d return [a, b]

  Reverse a linked list Difficulty:  Easy Accuracy:  73.11% Submissions:  384K+ Points:  2 Average Time:  30m You are given the  head  of a singly  linked list . You have to  reverse  the linked list and return the  head  of the reversed list. Examples: Input: Output: 4 -> 3 -> 2 -> 1 Explanation: After reversing the linkedList Input: Output: 8 -> 9 -> 10 -> 7 -> 2 Explanation: After reversing the linked list Input: Output: 8 Explanation: Constraints: 1 ≤ number of nodes ≤ 10 5 1 ≤ node->data ≤ 10 5 MyCODE: class Solution:     def reverseList(self, head):         prev=None         curr=head         while curr:             n_x =curr.next             curr.next=prev             prev=curr     ...
