warshall law order: a new matrix set to begin operation set i = 1 for all j if A [j, i] = 1, then for k = 1,2,3 ... ... n operation ah A [j, k]: = A [j, k]+ A [i, k] i++ if i < = n turn on the continuing need: 1. Enter the Matrix, with two-dimensional array, we can consider global variables 2. set matrix maximum nMax 3. for i from 0 to n-1 loop, as 1 per item to find, as a continuing operation, otherwise enhance: 1. input choice and can choose whether to continue operations 2. not confirm each line to increase modified option 3. use an array of strings, the result can be directly output
