Column, index, stored routine, and event names are not case-sensitive on any platform, nor are column aliases. However, names of logfile groups are case-sensitive. This differs from standard SQL. By default, table aliases are case-sensitive on Unix, but not so on Windows or macOS. The following statement would not work on Unix, because it refers to the alias both as a and as A:mysql> SELECT col_na...

手机号码一定是 1111 位数,前不含前导的 00。工具接收两个数 LL 和 RR,自动统计出 [L,R][L,R] 区间内所有满足条件的号码数量。LL 和 RR 也是 1111 位的手机号码。 套路的数位DP。 维护前一个数,前前一个数即可。ll dp[11][10][10][2][2][2][2][2];vector<int> v; int len;void init(ll n) {v.clear();while (n) v.push_back(n % 10), n /= 10;reverse(v.begin(), v.end());len = v.size(); }ll dfs(int cur, int x, int y, bo...
