Please answer the ques in python with showing the answers ( There is only 1 ques in 2 steps) Step 1: Demonstrate your knowledge of zip and f-strings in your solution Given 2 related lists : names=['Joe', 'Amy', 'Lil', 'Poe', 'Ali', 'Sid']                       grades=[65, 63, 89, 96, 59, 81] Write a program to output who passed and who failed. Passing is greater than or equal to 65. Output: Joe, you passed! Amy, you need to study more! Lil, you passed! Poe, you passed! Ali, you need to study more! Sid, you passed!   Step 2: Demonstrate your ability to nest a for loop inside a for loop. Create 2 lists:       fruits = apple, banana, cherry             descriptions = sweet, tasty Write the program whose output is:   Output: sweet apple sweet banana sweet cherry tasty apple tasty banana tasty cherry

Depth First Search

Depth-first search (DFS) also known as Depth First traversal is an algorithm used to traverse or search the nodes in a tree or graph data structure. Traversal usually means visiting all the nodes of a graph. DFS performs in a depth-ward manner. It uses a stack to remember the vertices it has visited. The search starts from the root node, where any arbitrary node is selected as a root node in a graph, and then each node is explored along each branch before performing backtracking. The DFS algorithm uses a recursive technique by following the idea of backtracking. DFS algorithm does this by performing an in-depth search of all the nodes by traversing in a forward direction. If the required node is not found, it starts backtracking to previously visited nodes.
