WebSep 6, 2024 · The XOR Function In addition to the OR function, there is also an exclusive OR function. This is called the XOR function. The XOR function was introduced with the Excel 2013 version. This function can take some effort to understand, so a practical example is shown. The structure of the XOR function is the same as the OR function. WebAug 18, 2024 · Explanation: The representation of given Binary Tree is as follows: The following pair of nodes have a Bitwise XOR of edges in the path connecting them as K = 0: Pair 1: (1, 4) = (3 ^ 3) = 0 Pair 2: (1, 8) = (2 ^ 1 ^ 3) = 0 Pair 3: (1, 7) = (2 ^ 2) = 0 Recommended: Please try your approach on {IDE} first, before moving on to the solution.
