```cpp
#include<stdio.h>
struct room{
int is,abs;
};
int n,m,now,ans;
room f[100000][110];//房间数据
int l[10000];//每层楼有楼梯的房间的个数
int round(int n,int now,int abs){//用来逆时针寻找
int count = 1;
while(count<=abs){
now = now%m+1;
if(f[n][now].is==1)count++;
}
return now;
}
void act(int n){//更改now的值
if(f[n][now].is==1){
int exact = f[n][now].abs;
int ext = (exact-1)%l[n]+1;
now = round(n,now,ext-1);
}
else{
int exact = f[n][now].abs;
int ext = (exact-1)%l[n]+1;
now = round(n,now,ext);
}
}
int main(){
scanf("%d%d",&n,&m);
for(int i = 1;i<=n;i++){
for(int j = 1;j<=m;j++){
scanf("%d%d",&f[i][j].is,&f[i][j].abs);
l[i]+=f[i][j].is;//带楼梯的房间数
}
}
scanf("%d",&now);
now++;//序号从零开始
for(int i = 1;i<=n;i++){
ans+=f[i][now].abs;
ans%=20123;
act(i);
}
printf("%d",ans);
return 0;
}

abs是关键语句，要换一个
