Array(2)
因为以后的很多有关数组的面试题都离不开增删改查，所以基本的逻辑语句是要会的比如插入的时候
first to create a new space for inserting element.
then shift all elments one index from that index to the right
we first need to shift all the elements from that index onwards one position to the right.
We do that by shifting each element one index to the right.
- make sense (if it doesn't make sense to keep it in the inventory anymore.)
- inventory
- given index :at any given index inside the Array.
- kept track of: as we've kept track of it in our length variable
- length variable
- past ( past the current last element.)
All we need to do for inserting an element at the end is to assign the new element to one index past the current last element. - pretty much the same
This is pretty much the same as we've already seen. - capacity [kəˈpæsəti]
- slots
- incremented
- shift it to the right by 2 index
- be proportional to
to be directly/inversely proportional to sth 与某事物成正比╱反比 - We do that by shifting each element one index to the right.
- onwards
- onwards from that index onwards one position
- proceed
- potentially
- required index
- be careful of：The main thing to be careful of is remembering that array.length gives you the total capacity of the Array.
- get around
- somehow :Can we use this information somehow to solve the problem?
- intertwine
