Week 180: 29 Aug 2022
You are given list of numbers, @n
and an integer $i
.
Write a script to trim the given list where element is less than or equal to the given integer.
Example 1 Input: @n = (1,4,2,3,5) and $i = 3 Output: (4,5) Example 2 Input: @n = (9,0,6,2,3,8,5) and $i = 4 Output: (9,6,8,5)
Well, that was easy. This:
grep { $_ > $i } @ngives the required answer
