If we enter K in column J of row I to correspond to the row in exact overwrite, after column J of row I is filled with K, row I cannot enter k any more, and column J cannot enter k any more. column G [I, j] cannot enter k any more.

contain the first column are few and become sparse matrices, In this case, using r or c queries is a waste of time. Dancing Links uses a two-way Cyclic Cross-linked list to store the matrix. The size of the linked list decreases continuously during the search process, and r or c is not required for Traversing once. Two-way linked list deletion: L [R [x] = L [x]; R [L [x] = R [x]; The restoration of a two-way linked list is also simple: L [R [x] = x; R [L [x] = x; Knuth named the linked list tha
