The bucket is a slot in the unordered_set’s internal hash table where elements are stored.
Note: Buckets in unordered_set are numbered from 0 to n-1, where n is the total number of buckets.
Parameter: This is a mandatory parameter and specifies the value of the element whose bucket number is needed to know in the unordered_set container.
Return Value: This function returns the bucket number of the bucket in the unordered_set container where the element with value element is stored.

The Element 25 is present in the bucket: 3 The Element 5 is present in the bucket: 5 The Element 10 is present in the bucket: 10 The Element 15 is present in the bucket: 4 The Element 20 is present in the bucket: 9
