Given the following list of functions:
1. f(n) = 2n^1/n
2. g(n) = n^2 logn
3. h(n)=n^logn
4. i(n) = 2^2^log n

Looking for advice on system design interviews. What are some common scenarios or problems that come up, and what's the best way to approach them?

Given the changes to SAP stock price over a period of time as an array of distinct integers, count the number of spikes in the stock price which are counted as k-Spikes.

A k-Spike is an element that satisfies both the following conditions:

There are at least k elements from indices (0, -1) that are less than prices[i].

• There are at least k elements from indices (i+1, n-1) that are less than prices[i].

Count the number of k-Spikes in the given array.

Example

prices = [1, 2, 8, 5, 3, 4] k = 2

There are 2 k-Spikes:

• 8 at index 2 has (1, 2) to the left and (5, 3, 4) to the right that are less than 8.

• 5 at index 3 has (1, 2) to the left and (3, 4) to the right that are less than 5.

Output is : 2

In JavaScript, define "Scope" and list its various types.

The idea of scope controls how variables or objects are managed as being available in an application. There are two varieties of scope in JavaScript, as follows:

Global Scope: A variable with global scope is available across the entire programme. These variables can be accessed from anywhere in the programme because they are declared outside of any specific function.
