如何用C+编译出来一个9*9的数独解
#include typedef struct{ int line; int row; int num;}Node;int main(){ /* int a[9][9]={ {4,0,3,6,0,0,0,0,0}, {0,0,0,0,0,1,0,2,4}, {0,1,0,0,4,0,5,0,0}, {0,0,0,9,0,4,0,6,0}, {3,0,2,0,0,0,4,0,9}, {0,7,4,1,0,3,0,0,0}, {0,0,1,0,9,0,0,4,0}, {2,4,0,3,0,0,0,0,0}, {0,0,0,4,0,8,2,0,7}}; */ int a[9]...全部
