When Id has changed assign value 1

I've been trying to find either a Power Query code or DAX code that allows me to assign the value 1 when the ID within my column table has changed. So I have a table that has an ID column that has duplicated ID's and I want to create another column that holds the values of either 1 or 0 where 1 shows where in the row the ID has changed and 0 showing the duplicated ID's following after before the ID changes again.

    Hi Anonymous 

    Create a sample like this :

    Then create a calculated column to group .

    Group_Index = 
RANKX(FILTER(ALL('Table'),'Table'[GROUP]=EARLIER('Table'[GROUP])),[Index],,ASC)

    You will get a result like this :

    Finally , create a calculated column to compare the ID .

    True = 
var _1=SUMX(FILTER(ALL('Table'),'Table'[GROUP]=EARLIER('Table'[GROUP])&&'Table'[Index]=EARLIER('Table'[Index])),[ID])
var _2=SUMX(FILTER(ALL('Table'),'Table'[GROUP]=EARLIER('Table'[GROUP])&&'Table'[Index]=EARLIER('Table'[Index])-1),[ID])
var _minindex=MINX(FILTER(ALL('Table'),'Table'[GROUP]=EARLIER('Table'[GROUP])),[Index])
return
IF([Index]=_minindex|| _1= _2,0,  SUMX(FILTER(ALL('Table'),'Table'[GROUP]=EARLIER('Table'[GROUP])&&'Table'[Index]=EARLIER('Table'[Index])-1),[Group_Index]))

    The fianl result is like this :
