Ex 6 - Simulation 2-D and 3-D Arrays by using just 1-D Array Use two one-dimensional arrays to simulate a two-dimensional array. Create the output as follows. Print it on a webpage. Output: Row 0:[0,0][0,1]{0,2][0,3] Row 1:[1,0][1,1][1,2][1,3] Row 2:[2,0](2,1][2,2][2,3] Row 3:[3,0][3,1][3,2][3,3] Ex 7 - Build a Simple JavaScript Clock Use the system's Date object to buid a simple clock as the following: 21:24:05 Hint: we can make use of

In addition, we make use of the document.getElementById("txt').innerHTML=h+":"+m+":"+s to locate the layer, and try to update it with the innerHTML properties. Finally we call the startTime() function recursively by using a timer t=setTimeout('startTime()',500) so as to animate the clock
