How to draw Taiji and Bagua symbol with GLSL
Taiji not only is a very interesting concept but also has a beautiful symbol. In this article I will try to replicate it using GLSL 
Collection of bit mask operation
I have collected a few popular and useful bit operations 
Closest Subsequence Sum
Given a list of integers and a target number, the problem is to find the closest subsequence of that list that add up to the target number, return the sum of that subsequence 
Minimum Number of K Consecutive Bit Flips
Given an array of 0s and 1s and an integer k, the problem is to find the minimum number of times a k-length sequence of bits need to be flipped (i.e. 0s to 1s or 1s to 0s) in order to obtain an array of all 1s 
Minimum One Bit Operations to Make Integers Zero
Given an array of integers, the problem is to find the minimum number of operations needed to make all the integers in the array 0 by performing only one bit operation (flipping one bit) at a time
