Bitwise Right Shift
Summary
The problem involves performing a bitwise right shift operation on a given number. The goal is to shift the bits of the number to the right by a specified number of positions, filling with zeros if necessary.
Detailed Explanation
To solve this problem, we can use the bitwise right shift operator (>>) in programming languages that support it (such as Java, C++, and JavaScript). This operator shifts the bits of the number to the right by the specified number of positions. For example, if we have a binary number 1010 and we want to shift it to the right by 2 positions, the result would be 0010.
Here's a step-by-step breakdown of the solution:
- Take an integer as input.
- Calculate the bitwise right shift of the integer using the >> operator in your chosen programming language.
- Return the shifted value.
Time complexity: O(1) Space complexity: O(1)
