Q2. Async and await difference
Ans. 
Async and await are keywords in JavaScript used for handling asynchronous operations.
• Async is used to define a function as asynchronous, allowing it to use the await keyword.

• Await is used to pause the execution of an async function until a Promise is settled.

• Async functions always return a Promise, which resolves with the value returned by the function.

• Using async/await makes asynchronous code easier to read and write

Your task is to add these two numbers and print the ...read more
Ans. Naive Method
We will use the naive method to add two linked lists. While adding two numbers, we always add digits in the right to left manner. So first, we will reverse both linked lists so that we can easily process the number in this manner.
 
We will be storing the result of the addition in a different linked list. We will start adding the nodes of both linked lists and use another variable ‘carry’ to keep track o...read more

Your task is to find if the g...read more
Ans. DFS Approach (Slow)
There is a cycle in the graph only if there is a back edge (back edge is an edge that connects a vertex to another vertex that is discovered before it's parent) present in the graph. To detect a back edge, we will keep track of vertices that have been already visited. If we reach a vertex that is already visited and is not the parent vertex of the current vertex, then there is a cycle in the graph.&n...read more

Ans. Brute Force
We will iterate through all possible boundaries of the subarrays in the given array with the help of two nested loops. 
 
Then, we will iterate through each subarray with the help of another loop and find the sum of the subarray. We will maintain the maximum subarray sum through our iterations and finally return it.
