A 题水题,如果n #include #include using namespace std; int main() { int n,ans; scanf("%d",&n); if(n>=0) printf("%d\n",n); else { n=-n; ans=-(n/100*10+min(n%10,n/10%10)); pri

D 题 SOL：就是要寻找满足某一条件的不同字串个数。   后缀数组解决！！！ #include #include #include using namespace std; const int MAXN=2010; char r[MAXN]; int sa[MAXN]; int wa[MAXN],wb[MAXN],wv[MAXN],ws[MAXN];
