Append numbers at same position in strings

Append numbers at same position in strings is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.

Task

Given three lists:
list1 = [1,2,3,4,5,6,7,8,9]
list2 = [10,11,12,13,14,15,16,17,18]
list3 = [19,20,21,22,23,24,25,26,27]
Turn the numbers them into strings and concatenate them.
The result should be:
list = [11019,21120,31221,41322,51423,61524,71625,81726,91827]

11l

V list1 = [1, 2, 3, 4, 5, 6, 7, 8, 9]
V list2 = [10, 11, 12, 13, 14, 15, 16, 17, 18]
V list3 = [19, 20, 21, 22, 23, 24, 25, 26, 27]

print(zip(list1, list2, list3).map((n1, n2, n3) -> String(n1)‘’n2‘’n3))

Output:

[11019, 21120, 31221, 41322, 51423, 61524, 71625, 81726, 91827]

Using the basic instruction set:

≪ 3 →LIST → lists 
   ≪ { } 1 lists 1 GET SIZE FOR j 
        "" 1 3 FOR k lists k GET j GET →STR + NEXT STR→ + NEXT 
≫ ≫ 'TASK' STO

Using the extended instruction set introduced in 2003:

Works with: HP version 49

≪ 3 ≪ →STR + + STR→ ≫ DOLIST
