LeetCode 136: Single Number — Step-by-Step Visual Trace
📰 Dev.to · tracelit
Learn to solve the Single Number problem on LeetCode using bitwise operations to find the single element in an array of integers where every element appears twice except for one.
Action Steps
- Read the problem statement carefully to understand the constraints and requirements.
- Use the XOR bitwise operation to find the single number, as XOR of all elements will give the single number.
- Initialize a variable to store the result and iterate over the array, performing XOR operation on each element.
- Return the result, which is the single number that appears only once in the array.
- Test the solution with example inputs to verify its correctness.
