I want to position the Example 1 column bellow the Algorithm and Example 2 in right to the Algorithm.

I put hspace*{-9cm} left move the Example 1 column left, but not moves.

• Why don't you just put it into the same column if is supposed to sit below? – user121799 Jul 23 '18 at 16:56
• @marmot As they are different block(one is algorithm and one is example) I want to put in separate. – alhelal Jul 23 '18 at 17:03
• the position of the exampleblock after an hspace is the same as the position after abc it does not move to the right or left as it starts a new pararaph, below, the \hspace* here just starts a (white) paragraph with no text. – David Carlisle Jul 23 '18 at 18:19

Is this the layout you are looking for?

And as already said for you previous question: you don't need xcolor with beamer
