(a);// Create the string '1' + 1,111 times '0', which is// equivalent to the decimal integral value 10^1111.// (This is the cube root of 10^3333.)std::fill(str_control.begin()+1U,str_control.begin()+1U+1111U,'0');str_control.front()='1';str_control.back()='\0';...
The input is assumed to be a 32-bit signed integer. Your function should return 0 when the reversed integer overflows. 这道题很简单,题意就不说了,我的做法是把数字转化为字符串,然后反转字符串,Java中有StringBuilder,C++中有STL可以直接反转,假如超出范围,按照题意直接返回0即可。
