Find the repeating number in an array.

• Iterate through the array and store each element in a hash table or set.

• If an element is already present in the hash table, it is a repeating number.

• Alternatively, sort the array and check for adjacent elements with the same value.

• Time complexity: O(n) or O(nlogn) depending on the approach used.

Paging and segmentation are memory management techniques used by operating systems.

• Paging divides memory into fixed-size pages and stores data in these pages.

• Segmentation divides memory into logical segments and stores data in these segments.

• Paging is simpler and more efficient, but can lead to external fragmentation.

• Segmentation is more flexible, but can lead to internal fragmentation.

• Both techniques are used to manag
