CORS allows web applications to make requests to a different domain than the one it originated from.
CORS is enabled on the server side by setting the 'Access-Control-Allow-Origin' header to specify which domains are allowed to make requests.
Options requests are sent by the browser to check if the server allows the actual request. The server should respond with the appropriate headers.
CORS can be configured to allow spe...

Binary Search has a time complexity of O(log n) and is derived from dividing the search space in half at each step.
Binary Search is a search algorithm that works on sorted arrays.
It starts by comparing the target value to the middle element of the array.
If the target value is smaller, the search continues on the lower half of the array.
If the target value is larger, the search continues on the upper half of the array.

QuickSort is a sorting algorithm that uses divide and conquer approach.
Choose a pivot element from the array
Partition the array into two sub-arrays, one with elements less than the pivot and one with elements greater than the pivot
Recursively apply the above steps to the sub-arrays
Combine the sorted sub-arrays to get the final sorted array
Code for Fibonacci Series using Recursion, Iteration and Dynamic Programming
Recursion: Define a function that calls itself with the previous two numbers in the series as arguments
Iteration: Use a loop to calculate the series by adding the previous two numbers in each iteration
Dynamic Programming: Store the previous two numbers in variables and use them to calculate the next number in the series
Implementing a Queue using Stacks
Use two stacks to implement a queue
Push elements onto the first stack
When dequeuing, pop all elements from the first stack and push onto the second stack
Pop the top element from the second stack to dequeue
If the second stack is empty, pop all elements from the first stack and push onto the second stack
MergeSort is a divide and conquer algorithm that sorts an array of strings.
Divide the array into two halves
Recursively sort the two halves
Merge the sorted halves
Counting Sort is a sorting algorithm that sorts elements by counting the number of occurrences of each unique element.
Count the occurrences of each element in the array
Calculate the cumulative sum of the counts
Place each element in the sorted array based on its count and cumulative sum
Time complexity is O(n+k) where n is the number of elements and k is the range of input
Example: Sort an array of strings based on their
Chrome uses an algorithm to predict and suggest words based on user input.
Chrome's algorithm uses a combination of user history, bookmarks, and popular searches to predict and suggest words.
The algorithm also takes into account the frequency and recency of the user's input.
Chrome's suggestion feature is powered by Google's Autocomplete API, which uses machine learning to predict and suggest words.
The suggestions are di...
