If you read about __builtin_clzll in http://gcc.gnu.org/onlinedocs/gcc-4.1.2/gcc/Other-Builtins.html — Built-in Function: int __builtin_clzll (unsigned long long x) Returns the number of leading 0-bits in x, starting at the most significant bit position. If x is 0, the result is undefined. From https://cs.stackexchange.com/a/29510, The maximum possible XOR of any two integers from an interval [l, r] can … Read more
XORing N copies of K together produces K if N is odd and 0 if N is even. K ^ K == 0, 0 ^ K == K, and it just alternates between those results with every additional K. (Your code is currently XORing n+1 copies of k together, which I’m guessing is a mistake.) … Read more
I measured with the following code. public static void main(String[] args) { boolean myVariable = true; long startTime = 0; long endTime = 0; long duration1 = 0; long duration2 = 0; for(int i=0; i<1000; i++) { startTime = System.nanoTime(); myVariable = !myVariable; endTime = System.nanoTime(); duration1 += (endTime – startTime); startTime = System.nanoTime(); myVariable … Read more
The call to check to see if the function was returning properly is flawed. To fix it place () at the end of the function name. 1 solved Strange response when answering a y or Y, n or N
That is because you re hitting the MAXIMUM INTEGER LIMIT which is 2147483647 From the PHP Docs… The maximum value depends on the system. 32 bit systems have a maximum signed integer range of -2147483648 to 2147483647. So for example on such a system, intval(‘1000000000000’) will return 2147483647. The maximum signed integer value for 64 … Read more
Introduction The XOR operation is a logical operation in programming that compares two numbers and returns a boolean value. In PHP, the XOR operation can be used to compare two numbers and determine if they are equal or not. This tutorial will explain how to use the XOR operation in PHP to compare two numbers … Read more
