1:使用长度为16的字符串数组对应16进制的16个字母:string HEX = "0123456789abcdef"; 2:为了每次提取4个长度的二进制,我们不用一个一个除,只需要把十进制和0xf做与操作即可,然后每次把十进制往右移4位。与操作取出来的值范围是0~15,我们取对应的HEX的下标。 参考代码: classSolution{ public: stringtoHex(i...
Given an integer, write an algorithm to convert it to hexadecimal. For negative integer,two’s complementmethod is used. Note: All letters in hexadecimal (a-f) must be in lowercase. The hexadecimal string must not contain extra leading0s. If the number is zero, it is represented by a si...
The hexadecimal string must not contain extra leading0s. If the number is zero, it is represented by a single zero character'0'; otherwise, the first character in the hexadecimal string will not be the zero character. The given number is guaranteed to fit within the range of a 32-bit si...
