分情况,三个花色相同,两个花色相同,然后里面再分。。。。。。
#include<bits/stdc++.h> using namespace std; typedef long long ll; char str[3][2]; int a[3]; int main(){ cin>>str[0]>>str[1]>>str[2]; for(int i=0;i<3;i++){ a[i]=str[i][0]-‘0‘; } if(str[0][1]==str[1][1]&&str[0][1]==str[2][1]){ sort(a,a+3); if(a[0]==a[1]&&a[1]==a[2]){ cout<<"0\n"; return 0; } if(a[0]+1==a[1]&&a[1]+1==a[2]){ cout<<"0\n"; return 0; } else if(a[0]+1==a[1]||a[1]+1==a[2]){ cout<<"1\n"; return 0; } else if(a[0]==a[1]||a[1]==a[2]||a[2]==a[0]){ cout<<"1\n"; return 0; } } if(str[0][1]==str[1][1]&&abs(a[0]-a[1])<=2){ cout<<"1\n"; return 0; } if(str[0][1]==str[2][1]&&abs(a[0]-a[2])<=2){ cout<<"1\n"; return 0; } if(str[1][1]==str[2][1]&&abs(a[1]-a[2])<=2){ cout<<"1\n"; return 0; } cout<<"2\n"; return 0; }

只看数组p,然后走完一页删一页,直接定位到下一个p[i]的页面
#include<bits/stdc++.h> using namespace std; typedef long long ll; const int M=1e5+100; ll n,m,k; ll p[M]; int main(){ scanf("%lld%lld%lld",&n,&m,&k); for(int i=0;i<m;i++){ scanf("%lld",&p[i]); } int cnt=0; int c=0; ll y=1; for(int i=0;i<m;){ int j=i; for(;j<m;j++){ if(p[j]>k*y+c) break; } c=j; if(j!=i)cnt++; if(p[j]>k*y+c) y=(p[j]-c+k-1)/k; i=j; } printf("%d\n",cnt); return 0; }
