IBM Technical Interview Questions and Answers
Question 1:- What is tree traversal?
Answer: Tree traversal is the process of visiting all of a tree’s nodes. We always begin at the root (head) node because all nodes are connected by edges (links). There are three methods for traversing a tree:
- In-order Traversal
- Pre-order Traversal
- Post-order Traversal
Question 2:- What is the Kruskal algorithm?
Answer:
This approach treats the graph as a forest, with each node representing a separate tree. A tree can only link to another tree if it has the lowest cost of all the choices and does not break MST characteristics.
Question 3:-What exactly is a queue?
Answer:
A queue, like a stack, is a typical data structure that arranges elements in sequential order. A queue employs the FIFO (First In First Out) mechanism, in which the first thing enqueued is also the first to be dequeued.
Question 4:- What do you mean by CLAUSE in SQL?
Answer:
In SQL, CLAUSE is used to limit the number of results returned by adding a condition to the query. As a result, you can filter rows from the complete collection of data using a CLAUSE.
Question 5:- What is a pipe and when does it actually be useful?
Answer:
Pipe: A pipe is typically a connection between two or more processes that are interconnected. It is a message-passing mechanism that is used for inter-process communication. A pipe makes it simple to transport data, such as the output of one programme activity, to another programme process.
Uses of Pipe:
It’s useful when two processes desire to communicate in one direction, i.e. inter-process communication (IPC)
Question 6:- Explain how to make a Python script Unix executable.
Answer:
#!/usr/bin/env python must be the first line of the script.
Question 7:- What is the meaning of a postfix expression?
Answer:
A postfix expression is one in which the operators come after the operands. The fundamental advantage of this style is that it eliminates the requirement for parentheses to group sub-expressions or to consider operator precedence. In postfix notation, the expression “a + b” will be written as “ab+.”
Question 8:- What is the Software Development Life Cycle, or SDLC?
Answer:-
SDLC, or Software Development Life Cycle, is a life cycle that represents the process of developing software. All aspects of software development are covered by SDLC models.
Question 9:- Write a program to find the maximum number of handshakes.
Question 10:- Write a program to sort the elements of an array.
