## [Solved] “Little girl and maximum XOR”

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

## [Solved] How to XOR n same numbers?

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

## [Solved] PHP XOR operation two numbers

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
