I. Base62(高精度进制转换) 比赛当时雷菊苣和队长俩人拿着大数板子摸了一百多行(然后在缺少大数板子的情况下雷菊苣一发过了orz) 今天补题随便摸了个高精度进制转换的板子交上去就过了还贼短,, 我好菜,佬们好厉害 ; int t[maxn], A[maxn]; char str1[maxn], str2[maxn]; int n, m; void solve() { int i, len, k; len = strlen(str1); ; --i) t[len--i] = str1[i]
You're given a permutation aa of length nn (1 \le n \le 10^51≤n≤105). For each i \in [1,n]i∈[1,n], construct a sequence s_isi by the following rules: s_i[1]=isi[1]=i; The length of s_isi is nn, and for each j \in [2, n]j∈[2,n], s_i[j] \le s_i[j-1]
