    You are trying to initialize the same table twice. First you are running 

     $(document).ready(function() {
    $('#example').dataTable( {
         "sPaginationType": "full_numbers",



    } );
} );

    Which is trying to initialize datatables on the table with the ID of example. Then you try to initialize it again here:

    var oTable = $('.exam').dataTable( {
        "oLanguage": {
            "sSearch": "Search all columns:"
        },
        "bStateSave": true,
        "fnInitComplete": function() {
            var oSettings = $('.exam').dataTable().fnSettings();
            for ( var i=0 ; i<oSettings.aoPreSearchCols.length ; i++ ){
                if(oSettings.aoPreSearchCols[i].sSearch.length>0){
                    $("tfoot input")[i].value = oSettings.aoPreSearchCols[i].sSearch;
                    $("tfoot input")[i].className = "";
                }
            }
        }
    } );

    Here you are initializing a table with the class of exam. The table with the class exam, and the ID of example are the same table in this case. The error is basically saying, hey I already initialized this table once, I cant do it again.

    Remove the first block of code and it should solve your problem.
