解题思路:
照着题目做
参考代码:
#include<bits/stdc++.h> using namespace std; struct m { int seat; char x; }mapp[100][100]; //记录位置 char ant; //记录方向 void f(const char s) //旋转函数 { if (s == 'L') { if (ant == 'L') ant = 'D'; else if (ant == 'D')ant = 'R'; else if (ant == 'R')ant = 'U'; else ant = 'L'; } else { if (ant == 'L') ant = 'U'; else if (ant == 'D')ant = 'L'; else if (ant == 'R')ant = 'D'; else ant = 'R'; } } void fxy(int& i, int& j) //每一步的操作 { if (mapp[i][j].seat == 0) { f('L'); mapp[i][j].seat = 1; mapp[i][j].x = '0'; if (ant == 'L') { j--; mapp[i][j].x = ant; } else if (ant == 'D') { i++; mapp[i][j].x = ant; } else if (ant == 'R') { j++; mapp[i][j].x = ant; } else { i--; mapp[i][j].x = ant; } } else { f('R'); mapp[i][j].seat = 0; mapp[i][j].x = '0'; if (ant == 'L') { j--; mapp[i][j].x = ant; } else if (ant == 'D') { i++; mapp[i][j].x = ant; } else if (ant == 'R') { j++; mapp[i][j].x = ant; } else { i--; mapp[i][j].x = ant; } } } int main() { int m, n, i=0, j=0,step; //i,j记录位置 cin >> m >> n; for (int h = 0; h < m; h++) { for (int l = 0; l < n; l++) { cin >> mapp[h][l].seat; } } cin >> i >> j; cin >> ant; mapp[i][j].x = ant; cin >> step; while (step--) { fxy(i,j); } cout << i << " " << j; }
