Check if next row in a list is different
Hi Guys,
I have a list, "A, B, C" and want to check if B <> A and C <> B (so n <> n +1).
Result should be {"B", "C").
I was trying with list.Accumulate, but I failed. It is possible with List.Accumulate or I should use another function ?
Thanks!
Best,
Jacek
For List.Accumulate
= List.Accumulate({1..List.Count(list)-1}, {}, (s,c)=> if list{c} <> list{c-1} then s & {list{c}} else s)

Use this - Here list is your your list
List.RemoveNulls(List.Generate(()=>[x=null,i=0, c= List.Count(list)], each [i]<[c], each [i=[i]+1, x=if list{i} <> list{i-1} then list{i} else null, c=[c]], each [x]))- jaryszekSuper User
Thank you.
So List.Accumulate is not possible?
