XSEED Education Interview Questions and Answers

Bubble sort is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order.

• Start from the first element and compare it with the next element

• If the first element is greater than the next element, swap them

• Repeat this process for all elements in the list

• Continue this process until no more swaps are needed

A Turing Machine is a theoretical device that can simulate any algorithmic computation.

• It was proposed by Alan Turing in 1936 as a model for computation.

• It consists of a tape, a head that can read and write symbols on the tape, and a set of rules for transitioning between states.

• It can simulate any algorithmic computation, making it a powerful tool for theoretical computer science.

• It is often used as a theoretical basi...read more

A hash function is a mathematical function that converts input data of arbitrary size into a fixed-size output.

• Hash functions are used to index data in hash tables.

• They are also used in cryptography to securely store passwords.

• Examples of hash functions include MD5, SHA-1, and SHA-256.

Guestimates around sizing

• Guestimates are rough estimates based on limited information

• They are useful in situations where precise data is not available

• Factors such as historical data, industry benchmarks, and expert opinions can be used to make guestimates

• Guestimates should be clearly communicated as rough estimates and not taken as exact figures

Fraction is a part of a whole number expressed in terms of numerator and denominator. Ratio is a comparison of two or more quantities.

• Fraction represents a part of a whole number, where numerator is the part and denominator is the whole.

• Ratio is a comparison of two or more quantities, expressed in the form of a:b or a/b.

• Fractions can be proper (numerator is less than denominator), improper (numerator is greater than or...read more
