I've been dealing with this problem for so long, I'm at the end of my tether.

The decision to allow private companies to access personal data is seen as the thin end of the wedge.

The ends justify the means.

I invested in an open-end fund.

I invested in a closed-end fund.

Finding the perfect balance between work and personal life is the end-all and be-all of happiness.

I live in the arse end of nowhere.

I used a double-ended queue to store the data.

They decided to throw him in at the deep end and see if he could handle the pressure.

I need to implement a data structure that supports both insertion and deletion at both ends, so I decided to use double-ended queues.
