My code works through 3 times but I don't know why I can't through another

php editor Youzi is here to answer your questions about the number of times the code is used. From your description, it seems that your code can only be used 3 times, but cannot be used by other methods. This problem could have several causes, such as license restrictions on the code or design issues with the code itself. To help you resolve this issue, we recommend that you check the license information for your code to make sure you have legal permission to use it. At the same time, you can also carefully check the design and implementation of the code to see if there are any restrictions or conditions that cause the limit on the number of uses. If the problem persists, we recommend that you seek help from the developer of the code or relevant technical support, who may be able to provide a more specific solution.

Question content

The question is: Little Code is currently playing ice adventure, a grid game with n rows and m columns. There are some insurmountable obstacles on some grids, and the rest of the grids are smooth ice.

Players are in it, allied on an unobstructed grid, and remain stationary. He will then follow the character as it moves up, down, left and right; when he holds down the character to move in one direction, the character will slide on the ice. Nature has asked you to move up here until there is an obstacle in the next grid in the direction of the character's movement or it exceeds the boundary of the map. Then the surface will continue to wait for Brother Xiaoyuan's next move.

Now given the positions of all obstacles on the map, the initial position of the small yard, and the action sequence of the small yard, please find the final location of the small yard.

This is my code

package main

import "fmt"
func yi(x,y int, s byte, a [][]int) (x1,y1 int){
    switch(s){
        
        case 'L':
            for{
                if y==0 || a[x][y-1]==1{
                    return x,y
                }
                y--

            }
        case 'R':
            for{
                if y==4 || a[x][y+1]==1{
                    return x,y
                }
                y++

            }
        case 'U':
            for{
                if x==0 || a[x-1][y]==1{
                    return x,y
                }
                x--

            }
        case 'D':
            for{
                if x==4 || a[x+1][y]==1{
                    return x,y
                }
                x++

            }

            
    }
    return x1,y1
}
func main() {

    var x,y,xc,yc,count int
    fmt.Scanf("%d %d",&x,&y)
    fmt.Scanf("%d %d",&xc,&yc)
    fmt.Scanf("%d",&count)
    // s:= make([]int,1,1)
    i:=count
        
    // }
    arr := make([][]int, x)
 for i := 0; i < x; i++ {
  arr[i] = make([]int, y)
 }
    // var arr [6][6]int
    for j:=0;j<i;j++{   
        var xt,yt int
        fmt.Scanf("%d %d",&xt,&yt)
        arr [xt-1][yt-1]=1
    }
    // for i:=0;i<x;i++{
    //     for j:=0;j<y;j++{
    //         fmt.Print(arr[i][j]," ")
    //     }
    //     fmt.Println()
    // }

    var kong string
    fmt.Scanf("%s",&kong)
    xf,yf:=xc-1,yc-1
    // xf,yf=yi(xf,yf,'R',arr)
    // fmt.Println(string(kong[7]))
    for i:=0; i<8; i++{
        xf,yf=yi(xf,yf,kong[i],arr)
        // fmt.Println(xf,yf)
        // func yi(x,y int, i int, s string, a *[5][5]int) (x1,y1 int){

    } 
    fmt.Println(xf+1,yf+1)

}

I'm trying to figure it out, but I need to find out where the problem is. Can you help me figure it out (I don't know the usage the professor used)

Workaround

If I understand correctly, I think your code may have forgotten to use varieties. In the code you write:

for i:=0; i<8; i++{
        xf,yf=yi(xf,yf,kong[i],arr)
        // fmt.println(xf,yf)
        // func yi(x,y int, i int, s string, a *[5][5]int) (x1,y1 int){

    }

I think 8 is a subjective const and I think it should be changed. Here is my solution, hope it helps:

package main

import "fmt"
func yi(x,y int, s byte, a [][]int) (x1,y1 int){
    switch(s){
        
        case 'L':
            for{
                if y==0 || a[x][y-1]==1{
                    return x,y
                }
                y--

            }
        case 'R':
            for{
                if y==4 || a[x][y+1]==1{
                    return x,y
                }
                y++

            }
        case 'U':
            for{
                if x==0 || a[x-1][y]==1{
                    return x,y
                }
                x--

            }
        case 'D':
            for{
                if x==4 || a[x+1][y]==1{
                    return x,y
                }
                x++

            }

            
    }
    return x1,y1
}
func main() {

    var x,y,xc,yc,count int
    fmt.Scanf("%d %d",&x,&y)
    fmt.Scanf("%d %d",&xc,&yc)
    fmt.Scanf("%d",&count)
    // s:= make([]int,1,1)
    i:=count
        
    // }
    arr := make([][]int, x)
 for i := 0; i < x; i++ {
  arr[i] = make([]int, y)
 }
    // var arr [6][6]int
    for j:=0;j<i;j++{   
        var xt,yt int
        fmt.Scanf("%d %d",&xt,&yt)
        arr [xt-1][yt-1]=1
    }
    // for i:=0;i<x;i++{
    //     for j:=0;j<y;j++{
    //         fmt.Print(arr[i][j]," ")
    //     }
    //     fmt.Println()
    // }

    var kong string
    fmt.Scanf("%s",&kong)
    xf,yf:=xc-1,yc-1
    // xf,yf=yi(xf,yf,'R',arr)
    // fmt.Println(string(kong[7]))
    for i:=0; i<count; i++{
        xf,yf=yi(xf,yf,kong[i],arr)
        // fmt.Println(xf,yf)
        // func yi(x,y int, i int, s string, a *[5][5]int) (x1,y1 int){

    } 
    fmt.Println(xf+1,yf+1)

}
