How To calculate the Number of Event on a new column With Reference with Date

[Anonymous]

I have a date, Code and Number Of Event Column . The Logic is This - WHen You have BB or BV in the Code code Column There should BE "1" on the Number of Event Colum but if we have BB or BV on Two consucative Days WE want to have "1' for the first Day and '0" For the Second Day. Example 
Date| Code|Number Of Event 
1/1/2001| BB| 1
1/2/2001| BB| 0
1/7/2001| BB| 1
1/8/2001| BB| 0
1/12/2001|BB|1
Please How Can I implement this Logic With Dax . I have Tried This IF([Code]="BB",1,0,IF([Code]="BB",1,0)) But It didnt Work
