02 Edit Distance: Find the edit distance between two strings.
03 Distinct Subsequences: Given a string S and a string T, count the number of distinct subsequences of T in S.
04 Maximum Sum Subarray: Find the sum of contiguous subarray within a one-dimensional array of numbers which has the largest sum
Section 8 Bit Manipulation Interview Questions
01 Bitwise and Shift Operators: Manipulate bits and shift bits to change values.
02 Single Number: Given an array of integers, every element appears twice except for one. Find that single one.
03 Sum of Two Integers: Calculate the sum of two integers a and b, but you are not allowed to use the operator + and -.
04 Number of 1 Bits: Take an unsigned integer and return the number of ’1' bits it has (also known as the Hamming weight.)
05 Reverse Bits: Reverse the bits of a given 32 bit unsigned integer.
06 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.

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 and Skillshare 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.

What if I’m not good with technology?
The majority of Mammoth Interactive students are complete beginners. Even if you feel like you know nothing about technology, you won’t feel left out. All technical concepts are described in simple terms while avoiding unnecessary jargon. Each course starts from scratch and builds up your knowledge substantially in steps. Students from age 5 to 70 have successfully completed our courses. And just in case you get stuck, you can always ask any questions under each lecture, which will be promptly answered by one of my team members.
What if I'm an experienced developer?
Stack Overflow's yearly developer survey found that developers over age 50 start to make less than their younger counterparts. Don't become one of the people affected by skill stagnation. Enroll in our school to future-proof your career for life. If you're an experienced developer, you will still benefit from Mammoth Interactive courses. By starting from scratch with each course, you will revisit the fundamentals and undo bad coding habits.
