Description

Data Structures + Algorithms to Crack the Coding Interview

Only in Coding Interview Cram: Must Know Algorithms and Questions, learn the best way to answer an interview question, look at the most commonly asked questions, and analyze time complexity of various algorithms.

Interview Question Solutions and Time Complexity

Learn through hands-on coding examples and learn to solve problems quickly.

Refresh your Kotlin knowledge and solve new problems with the most common beginner interview questions asked by FANG companies.

Algorithms & Data Structures - Ultimate Coding Interview Prep

Learn the most commonly asked questions by the likes of Facebook, Google, Amazon and Spotify for beginners.

Preparing for the Kotlin interview is hard. You need to understand not only concepts but also be able to articulate your thought process as you plan and execute a solution.

COURSE BREAKDOWN

Section 0: Introduction to Interview Questions

  • Course Overview

  • FizzBuzz: Print the numbers from 1 to 100 and for multiples of '3' print "Fizz" instead of the number and for the multiples of '5' print "Buzz".

Section 1: String/Array Interview Questions

  • Reverse Words in a String: Given an input string, reverse the string word by word.

  • Rotate Array: Rotate an array of n elements to the left by k steps.

  • Kth Largest Element in an Array: Find the kth largest element in an unsorted array. Note that it is the kth largest element in the sorted order, not the kth distinct element.

Section 2: Matrix Interview Questions

  • Set Matrix Zeroes: Given a 2D matrix, if an element is 0, set its entire row and column to 0. Do it in place.

  • Spiral Matrix: Given a 2D matrix, return all elements of the matrix in spiral order.

Section 3: Linked List Interview Questions

  • Implement a Queue Using a Linked List: Hit two data structures in one by implementing a queue and a linked list in one interview question.

Section 4: Tree Interview Questions

  • Build a Binary Tree - Learn about binary trees and BST as you implement a highly asked about data structure, the binary tree.

  • Delete a Tree Node

Section 5: Graph Interview Questions

  • Build a Graph: Each node in the graph contains a label and a list of its neighbors.

Section 6: Sorting and Time Complexity

  • Bubble Sort Algorithm: Sort a list with bubble sort.

  • Selection Sort Algorithm: Sort a list with selection sort.

  • Insertion Sort Algorithm: Sort a list with insertion sort.

  • Merge Sort Algorithm: Sort a list with Merge Sort.

  • Time Complexity of Different Sorting Algorithms: Learn the types of time complexity in Big-O Notation in order of horrible to good.

Section 7 Dynamic Programming Interview Questions

  • Coin Change: You are given coins of different denominations and a total amount of money amount. Write a function to compute the fewest number of coins that you need to make up that amount.

  • Edit Distance: Find the edit distance between two strings.

  • Distinct Subsequences: Given a string S and a string T, count the number of distinct subsequences of T in S.

Section 8 Bit Manipulation Interview Questions

  • Bitwise and Shift Operators: Manipulate bits and shift bits to change values.

  • Single Number: Given an array of integers, every element appears twice except for one. Find that single one.

  • Number of 1 Bits: Take an unsigned integer and return the number of ’1' bits it has (also known as the Hamming weight.

  • Bitwise AND of a Range: Given two non-negative long integers, a and b and given a <= b, find the bitwise AND of all integers from a and b.

Section 9 Combinations and Permutations Interview Questions

  • Permutations: Print all permutations of a given string.

  • Combinations: Print all combinations of a given string.

  • Letter Combinations of a Phone Number: Given a digit string, return all possible letter combinations that the number could represent on a phone board.

Section 10 Math Interview Questions

  • Reverse Integer: Reverse the digits of an integer n.

  • Palindrome Number: Determine whether an integer is a palindrome. Do this without extra space.

  • Excel Sheet Column Number: Given a column title from an Excel sheet, return its corresponding column number.

REVIEWS OF MAMMOTH COURSES

Captivating voice, easy to follow at a rapid pace, get some paper and fasten your seat-belts. I'm enjoying every second of this.

— PHILIP MURRAY

I have completed many Udemy tutorials. This one is the most outstanding one that I have seen thus far. It is doubtful that it could be topped. This is a superior tutorial. Amazing.
