I feel confident that both stream and block ciphers are valid answers, but I might be mixing up the definitions of transposition and substitution.

I think transposition ciphers are more about rearranging letters, so I'm not sure if that's really a symmetric encryption technique.

The key here is to focus on the core symmetric encryption algorithms like block and stream ciphers. Those are the bread and butter, so I'll make sure to select those for sure.

I'm a little confused - I thought the transposition cipher was more of a historical technique, not really used in modern symmetric encryption. I'll have to double-check my notes on that.

Okay, I've got this. Journal entries, whether debits or credits, are used to record transactions that affect the equity account. The key is understanding how each type of journal entry impacts equity.

I think the most efficient method is using a For loop with Auto-indexing. That's the option that seems the most straightforward and efficient to me.
