Може ли да ми помогнете да си довърша кода или поне да видя друг и да ги сравня?

Условието:

You will be given a list of integer numbers on the first input line. Until you receive "End" you will be given operations you have to apply on the list. The possible commands are:

Add {number} – add number at the end
Insert {number} {index}” – insert number at given index
Remove {index} – remove at index
Shift left {count} – first number becomes last ‘count’ times
Shift right {count} – last number becomes first ‘count’ times

Note: it is possible that the index given is outside of the bounds of the array. In that case print "Invalid index"
