WebExample 1: Input: N = 2 Output: 000000000000000000000000000010 Explanation: The binary representation of 2 is '10' but we need to print in 30 bits so append remaining 0's in the left. Example 2: Input: N = 5 Output: 000000000000000000000000000101 Explanation: The binary representation of 5 is '101'. Your Task: 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.

WebJun 6, 2024 · We can calculate f 1 ( p) in O ( log m) using the binary exponentation algorithm. Similarly for f 2 ( q) . In the first step of the algorithm, we need to calculate f 1 for every possible argument p and then sort the values. Thus, this step has complexity: O ( ⌈ m n ⌉ ( log m + log ⌈ m n ⌉)) = O ( ⌈ m n ⌉ log m)
