=ARRAYFORMULA(FLATTEN(SPLIT(JOIN(",", REPT(A2:A4&",", B2:B4)), ",")))

英文:

I would like to repeat a list in google sheets where each item is repeated a different number of times based on a value in a different cell.

What formula can I use to achieve this?

List:
Apple
Banana
Orange

Desired Output:
Apple
Apple
Banana
Banana
Banana
Banana
Orange
Orange
Orange

Items # of rept
Apple 2
Banana 4
Orange 3

=ARRAYFORMULA(FLATTEN(IF(SEQUENCE(ROWS(D2:D42),10),D2:D42)))

This is all I can think of but the 10 needs to be a custom value depending on the value associated with the unique cell in D2:D42.

=ARRAYFORMULA(TOCOL(SPLIT(JOIN(,REPT(A2:A&"ζ",B2:B)),"ζ")))
=ARRAYFORMULA(TOCOL(MAP(A2:A,B2:B,LAMBDA(a,b,IF(SEQUENCE(1,b),a))),3))
=TOCOL(MAP(A2:A,B2:B,LAMBDA(a,b,CHOOSECOLS(a,SEQUENCE(1,b,1,0)))),3)
英文:

Here are some options:

=ARRAYFORMULA(TOCOL(SPLIT(JOIN(,REPT(A2:A&"ζ",B2:B)),"ζ")))
=ARRAYFORMULA(TOCOL(MAP(A2:A,B2:B,LAMBDA(a,b,IF(SEQUENCE(1,b),a))),3))
=TOCOL(MAP(A2:A,B2:B,LAMBDA(a,b,CHOOSECOLS(a,SEQUENCE(1,b,1,0)))),3)
