WebThe task is to check if N is a power of 2. More formally, check if N can be expressed as 2x for some x. Example 1: Input: N = 1 Output: YES Explanation:1 is equal to 2 raised to 0 (20 = 1). Example 2: Input: N = 98 Output: NO Explanation: 98 cannot be obtained by any power of 2. Your Task:Your task is to complete the function isPowerofTwo ... WebJan 17, 2024 · 5 Answers. The best way to write this code is to qualify all column references. So I would recommend: SELECT b.N, (CASE WHEN b.P IS NULL THEN 'Root' WHEN (SELECT COUNT (*) FROM BST b2 WHERE b2.P = b.N) > 0 THEN 'Inner' ELSE 'Leaf' END) FROM bst b ORDER BY N; This makes it clear that inner query is a correlated …

WebSep 9, 2014 · Start with exponentiation by squaring, as you have. Perform the actual squaring in a 64-bit unsigned integer. Reduce modulo 673109 at each step to get back within the 32-bit range, as you do. Obviously that's a bit awkward if your C++ implementation doesn't have a 64 bit integer, although you can always fake one.
