Collect and sort square numbers in ascending order from three lists
Collect and sort square numbers in ascending order from three lists 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
Add and sort suare numbers in ascending order from three lists.
list[1] = [3,4,34,25,9,12,36,56,36]
list[2] = [2,8,81,169,34,55,76,49,7]
list[3] = [75,121,75,144,35,16,46,35]
