今天和大家聊的问题叫做 环绕字符串中唯一的子字符串,我们先来看题面: https://leetcode-cn.com/problems/unique-substrings-in-wraparound-string.../ We define the string s to be the infinite wraparound string of "abcdefghijklmnopqrstuvwxyz", so s will
However, if you want modulo arithmetic add comments as necessary noting the reliance on wraparound behavior

这25个安全漏洞被统称为BadAlloc,是由内存分配整数溢出( Integer Overflow)或环绕错误(Wraparound)引起的。
enough cout << vec[i] << '\n'; for (unsigned i = 0; i < vec.size(); i += 2) // risk wraparound
