解法二: classSolution{public:stringbaseNeg2(intN){stringres;while(N !=0) {intrem = N % (-2); N /=-2;if(rem <0) { rem +=2; N +=1; } res = to_string(rem) + res; }returnres ==""?"0": res; } }; 讨论:我们都知道对于一个正数来说,右移一位就相当于除以2,但是对于负...
The hexadecimal string must not contain extra leading 0s. 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...
