Please programmers in the house help a sister out of her dilemma. This assignment is very urgent could you please help me out? Below is the question:

Warshall developed the following efficient algorithm for calculating the matrix B+ = B+ BB+….+B!n from the Boolean Matrix B. write a Pascal program to implement the algorithm

1 Set a new matrix A=B
2 Set ! = 1
3 For all j, if A[j,i]=1 then for k=1, …., n set A[j,k] = A[j,k] + A[i, k]
4 Add 1 to i
5 If I _< n then go to step 3, otherwise stop
                     
Please Note: (_< means less than or equal to. I couldnt get the right sign from the fonts provided here) The lecturer insisted that it must be done in Pascal or C++ environment, the source code will also be copied and send to her mail. So please here is my email address in case  you want to send me the source code: cecegrace@gmail.com

Thanking you so much.
