function e = runtest(array,answer)
%runtest(array,answer)- calls array11(array) to get the result and %compares with the answer. and returns 1 if error and 0 if no error and %also prints out the test result.
	result = array11(array);
	 
	if(result == answer)
		e = 0;
		fprintf('		array11 {'); fprintf(' %s ',mat2str(array)); fprintf('} -->');fprintf('%d\n',result);
		 	
	else
		e = 1;
		fprintf('ERROR:array11 {');fprintf(' %s ',mat2str(array));fprintf('} -->%d<>%d\n',result,answer);
