136. Single Number XOR Method: Finding the Single Non-Repeated Number #leetcode #coding

we solve the problem of finding the single non-repeated number in an array using the XOR operation. XOR (exclusive OR) is a bitwise operation that cancels out paired elements, leaving the unique element behind. By iterating through the array and applying XOR to each element, repeated numbers nullify each other, revealing the solitary unpaired number efficiently. This approach ensures a linear runtime complexity (O(n)) and uses constant extra space, making it a concise and powerful solution for this problem. Watch to understand XOR's application and its effectiveness in solving unique number problems.
