review: `The breadth of algorithms covered is impressive. From basic sorting to advanced graph algorithms, everything is presented in an accessible way. The only suggestion I have is to add more real-world application examples for each algorithm.`,

review: `I got to know about Data Visualizer just a few days ago , yet i feel i learned a lot already . Great platform !!!`,
`Implementing a Queue using an array is a fundamental approach where we use a fixed-size or dynamic array to store elements while maintaining FIFO order. The array implementation requires careful handling of front and rear pointers to efficiently enqueue and dequeue elements.`,

`In a circular array implementation, we treat the array as circular to maximize space utilization. When either pointer reaches the end of the array, it wraps around to the beginning.`,

`Queues are widely used in scenarios like printer job scheduling, call center systems, and network packet handling where order preservation is crucial.`,

<strong>Circular Array Note:</strong> The modulo operation (<codeclassName="font-mono">% capacity</code>) enables the circular behavior by wrapping the pointer to the start when it reaches the end.
