类似的还有与操作bit_and、或操作bit_or。 2. 头文件 #include <functional> 3. 例子:对一个数组逐个进行异或操作 比如常见的问题:一个数组里只有1个数出现1次,其他数都出现2次。 这时可用异或操作找出这个只出现一次的数。 #include<iostream>#include<numeric>#include<functional>usingnamespacestd;intmain()...
BIT_XOR[it] Parents Aggregate Functions Window Functions Syntax BIT_XOR(expr) [over_clause] Contents Syntax Description Examples See Also Description Returns the bitwise XOR of all bits inexpr. The calculation is performed with 64-bit (BIGINT) precision. It is anaggregate function, and so can...
The operatorbit_xorcalculates the “xor” of all pixels of the input images bit by bit. The semantics of the “xor” operation corresponds to that of C for the respective types (signed char, unsigned char, short, unsigned short, int/long). The images must have the same size and pixel ...

Oracle 20c introduces new aggregate functions: BIT_AND_AGG() BIT_OR_AGG() BIT_XOR_AGG() This could be emulated by producing a big expression for each bit in a data type: -- Native support, assuming a is a TINYINT SELECT bit_and_agg(a) FR...
