Mentor Graphics Interview Questions and Answers
16 Interview questions
The bottom view of a binary tree shows the nodes visible when the tree is viewed from below.
Bottom view is determined by the horizontal distance from the root.
Nodes are printed from leftmost to rightmost at the lowest level.
Use a queue for level order traversal and a map to store nodes.
Example: For a tree with root 1, left child 2, right child 3, bottom view is [2, 1, 3].
Flip flop can be implemented using a multiplexer by selecting the input based on the control signal.
Use a 2:1 multiplexer to select between the current state and the next state
Connect the output of the multiplexer to the input of the flip flop
Control signal determines which input is passed through the multiplexer
Data entry can be used to input information into a system or database.
Identify the specific system or database where the data needs to be entered.
Ensure that the data being entered is accurate and complete.
Follow any specific guidelines or protocols for data entry.
Regularly review and update the entered data as needed.
Examples: entering customer information into a CRM system, inputting financial data into an accou...
The probability of getting heads maximum two times in a series of coin flips.
To calculate the probability, divide the number of favorable outcomes by the total number of possible outcomes.
In this case, the favorable outcomes are 0, 1, or 2 heads, and the total possible outcomes are 2^n, where n is the number of coin flips.
For example, if we flip a coin 3 times, the favorable outcomes are HHT, HTH, THH, HHH, TTH, T...
To find the average speed for the whole trip, we need to know the distance and the time taken for the trip.
Average speed = Total distance / Total time
If the distance and time for the trip are known, the average speed can be calculated.
If only the average speed while going is known, we cannot determine the speed of the whole trip without additional information.
Use a sensor to detect the direction of rotation of a circular wheel by monitoring signal changes as it rotates.
Use an incremental encoder that generates pulses as the wheel rotates.
Determine direction by comparing the phase of two output signals (A and B).
If signal A leads signal B, the wheel rotates clockwise; if B leads A, it rotates counterclockwise.
Example: In a rotary encoder, the quadrature output can indic...
To find a number in a matrix where all rows and columns are sorted non-decreasingly. Complexity of the solution.
Use binary search to find the number in each row and column
Start from the top-right corner or bottom-left corner to optimize search
Time complexity: O(m log n) or O(n log m) depending on the starting corner
To find the starting point of a loop in a linked list, use Floyd's cycle-finding algorithm.
Use two pointers, one moving at twice the speed of the other.
When they meet, move one pointer to the head of the list and keep the other at the meeting point.
Move both pointers one step at a time until they meet again, which is the starting point of the loop.
To check if a directed graph is cyclic or not
Use Depth First Search (DFS) algorithm to traverse the graph
Maintain a visited set to keep track of visited nodes
Maintain a recursion stack to keep track of nodes in the current DFS traversal
If a node is visited and is already in the recursion stack, then the graph is cyclic
If DFS traversal completes without finding a cycle, then the graph is acyclic
Check if a binary tree is a binary search tree or not.
Traverse the tree in-order and check if the values are in ascending order.
For each node, check if its value is greater than the maximum value of its left subtree and less than the minimum value of its right subtree.
Use recursion to check if all nodes in the tree satisfy the above condition.
