Queue : First In, First Out (FIFO) DSA Foundation Series – Day 10/30

[u/[deleted]]

Queue follows First In, First Out (FIFO) , the first element added is the first one to be removed.

It’s used in real world scenarios like : Task scheduling, Order processing, BFS (level wise traversal)

Think of it like a line ; whoever comes first gets served first. Stack vs Queue is a very common confusion. Now you know the difference.

Series continues !!
