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.
