Nettet题目四 allOddBits (int x) 本题的题意是如果x的所有奇数位都为1，那么就返回1，反之为0。 所以思路就是构建一个t ，t的所有奇数位都是1，然后 (x&t ) == t 即可。 int allOddBits(int x) { int val = 0xAA; // 8bit 1010 1010 int aval = 0xAA << 8 0xAA; // 16 bit int bval = aval << 16 aval; // 32 bit int res = (x & bval) ^ bval; return !res; } 通过&可以 … Nettet15. mar. 2011 · int result = (1 << x); result += 4; return result; } FLOATING POINT CODING RULES For the problems that require you to implent floating-point operations, …
