问题描述

我换成了3D的std ::矢量一个三维阵列中的我的code函数,它的进入一个无限循环.Could你给我一个提示,我真的需要使用一个载体,而不是一个array.Thanks :)结果
我最初的code是:

I replaced a 3D array with a 3D std::vector in my code function and it's entering a infinite loop .Could you give me a hint,I really need to use a vector instead an array.Thanks:)
My initial code was:

//arr is a 3D array of a sudoku table,the 3 rd dimension is for keeping values 0 to 13  
//for a cell, and when I assign values I start from index 1 to 12

bool sol(int arr[12][12][13]) {
int row,col;

if(!find_empty(arr,row,col)) return true;

for(int i=1;i< 12;i++) { //for digits 1 to 12
    if(is_working(arr,row,col,arr[row][col][i]) ) {   //if i can put the value in a cell
        arr[row][col][0] = arr[row][col][i];  //replace the first element for a cell with that value
     //here I want to use vector because I want to use an ac3 algorithm 
     //and remove those values that not satisfy constraints and shrink domain size having less values to verify with backtrack

        if(sol(arr)) return true;

        arr[row][col][0] = 0;
    }
}

return false;//if not backtrack
}

我替换改编

std::vector<std::vector<std::vector<int> > > vec;
vec.resize(12);
for(int i=0;i<12;i++)
{
vec[i].resize(12);
for(int j=0;j<12;j++)
{
    vec[i][j].resize(13);
    for(int k=0;k<13;k++)
        vec[i][j][k]=table[i][j][k];
   }
} 


bool sol(std::vector<std::vector<std::vector<int> > >& vec) {
int row,col;

if(!find_empty(vec,row,col)) return true;

for(int i=1;i< vec[row][col].size();i++) {//for remainig values in domain
    if(is_working(vec,row,col,vec[row][col][i]) ) {//same as above but having less values to verify for
        vec[row][col][0] = vec[row][col][i];

        if(sol(vec)) return true;

        vec[row][col][0] = 0;
    }
}

return false;
}

和现在它进入了一个死循环!初始code没有错误,这是在我替换改编 VEC 出现一个简单的backtracking.The问题。你能给我如何更换3D一些建议改编与三维矢量

and now it's entering a infinite loop!The initial code has no errors,it's a simple backtracking.The problem appears after I replace arr with vec.Could you give me some advice on how to replace 3D arr with an 3D vector

推荐答案

我已经解决了疑难问题使用向量的矩阵,而不是一个三维向量,它的伟大工程:D

I have solved the problem.I used a matrix of vectors instead a 3D vector and it works great :D
