ruby - Get all three digit numbers from array and store in new array -


i need regular expression matches 3 digit numbers in following array. need result new array.

input:

my_array = [111,45456,456,74897,787,45466,789,6587,784,234,456,4658,4587,235,456]

desired output:

new_array = [111,456,787,789,784,234,456,235,456]

why regular expression on numbers? can select numbers less 1000 , greater 99.

my_array.select { |n| n<1000 && n>99 }
