WebJan 8, 2024 · You can change your array packing to use map instead. n, k, q = map (int, input ().strip ().split (' ')) When popping the last element you don't need to pass an argument. Rather than popping each element, you can perform two slices and an addition. You would also have to use the modulo operator, %, for when k ≥ n. k %= n a = a [-k:] + a [:-k] WebDec 31, 2024 · To answer the question in the title, you can "shift" an array with the substring/subarray notation. shift itself works with just the positional parameters. $ a= (a b c d e) $ a= ("$ {a [@]:1}") $ echo "$ {a [@]}" b c d e Similarly, to 'pop' the last item off the array: a= ("$ {a [@]:0:$ {#a [@]} - 1}" ) or unset "a [$ {#a [@]}-1]"
