Arithmetic and Logical Right Shifts

The logical right shift means shifting the bits to the right, and MSB(most significant bit) becomes 0. The arithmetic right shift means shifting the bits to the right, and MSB is the same as in the original number.

Bitwise Left Shifts

The left-shift operator causes the bits in shift-expression to be shifted to the left by the number of positions specified by additive-expression. The bit positions that have been vacated by the shift operation are zero-filled.

Introduction to Bit Shifting

A bit shift is a Bitwise operation where the order of a series of bits is moved, either to the left or right, to efficiently perform a mathematical operation.

Solution Review: Missing Number

We solved the problem using lookup (hashtable), using the mathematical formula. Let's solve this more efficiently using bit-level operations with XOR and then optimize the solution.

Challenge 2: Missing Number

In this article, we'll learn various ways to find the missing number in an array. We use a memoization approach, a mathematical approach, and the most optimized way using the XOR operator.

Solution Review: Single Number

Single Number coding question, can be easily solved with XOR bitwise technique with linear time complexity.
