Computer Fundamentals

Q1. Flatten a binary tree
Ans. 
Flatten a binary tree by converting it into a linked list in-place.
• Use a recursive approach to flatten the binary tree.

• Traverse the tree in a pre-order manner and keep track of the previous node.

• Set the left child of each node to null and the right child to the next node in the linked list.

• Example: Input: 1 -> 2 -> 5 -> 3 -> 4 -> null, Output: 1 -> null -> 2 -> null -> 3 -> null -> 4 -> null -> 5 -> null

Largest Cycle in Maze Problem Statement
Given a maze represented by 'N' cells numbered from 0 to N-1, and an array arr of 'N' integers where arr[i] denotes the cell number that can be reached from the 'i'...read more
Ans. 
Identify the length of the largest cycle in a maze represented by cells and an array of integers.
• Iterate through each cell and find the cycle length using DFS or Floyd's Tortoise and Hare algorithm.

• Handle self-cycles and cells with no exit by checking arr[i] = i and arr[i] = -1 respectively.

• Output the length of the largest cycle found or -1 if no cycles exist.

Q2. 
Ninja and the Maze Problem Statement
Ninja is stuck in a maze represented as a 2D grid. He can move in four directions (Up, Down, Left, Right) until he hits a wall ('1'). Once stopped, he can choose a new...read more
Ans. 
Determine if Ninja can reach the destination in a maze by moving in four directions until hitting a wall.
• Create a function to traverse the maze using depth-first search or breadth-first search.

• Keep track of visited cells to avoid infinite loops.

• Return 'True' if destination is reachable, 'False' otherwise.
