Hi guys,
Short question. I have an array of values, returned by using filter function which is {20,30,40,10,60}. I would like to deduct 60 from this such that the output is {0,0,30,10,60}. Is there a way to do this? I was using scan and lambda function but residuals are accumulated. (Results were {0,0,30,40,100})

I'm afraid I don't understand SCAN and LAMBDA... yet... but try:
=LET(a,MMULT(N(SEQUENCE(ROWS(B2#))>=SEQUENCE(,ROWS(B2#))),N(+B2#))-SEQUENCE(5,,60,0),IF(a<0,0,a))

None of us get paid for helping you... we do this for fun. So DON'T FORGET to say "Thank You" to all who have freely given some of their time to help YOU.
Temporary addition of accented to illustrate ongoing problem to the TT: L? fh?ile P?draig sona dhaoibh
or:
=LET(d,B2#,r,ROWS(d),a,MMULT(N(SEQUENCE(r)>=SEQUENCE(,r)),N(+d))-SEQUENCE(r,,60,0),IF(a<0,0,a))
Thanks for the quick follow up. Unfortunately the output array isn't what I'm looking for. I would like to get {0,0,30,10,60}. Your formula returns the same as the scan/lambda output I have..
Or:
=LET(a,FILTER(A2:A6,A2:A6>0),IF(SCAN(C2,a,LAMBDA(x,y,x+y))<0,0,SCAN(C2,a,LAMBDA(x,y,x+y))))
EDIT: Ignore! I misunderstood the requirement.

Hahaha. Trying to do 3 things at once.... this is a mess... sorry... but the other 2 are going fine though (not Excel-related)!!
Please explain why the third value should be 30.
(20+30+40)-60. From that point onwards.. return the value from column B.
Yep , Thats why third value is 30. Its essentially FIFO (first in first out).
A bit convoluted... but:
=LET(a,B2#,d,C2,b,SUBTOTAL(9,OFFSET(B2,,,SEQUENCE(ROWS(B2#))))+d,IF(b<0,0,IF(b<a,b,a)))
or, non-volatile:
=LET(a,B2#,d,C2,b,MMULT(N(SEQUENCE(ROWS(B2#))>=SEQUENCE(,ROWS(B2#))),N(+B2#))+d,IF(b<0,0,IF(b<a,b,a)))
and of course, you can drop your incomprehensible SCAN/LAMBDA into that, too:
=LET(a,B2#,d,C2,b,SCAN(d,a,LAMBDA(x,y,x+y)),IF(b<0,0,IF(b<a,b,a)))
Thanks mate, will put in effort to learn all three type! Consider this solved.
You're welcome.
It would be very nice if you were to just click the Add Reputation button at the foot of any of the posts of members who helped you reach a solution.
Finally, if that takes care of your original question, please select "Thread Tools" from the menu link (just above the first post in the thread) and mark this thread as SOLVED.
