Sort an array containing 0, 1, and 2.
Use a sorting algorithm like quicksort or mergesort.
Count the occurrences of 0s, 1s, and 2s, then reconstruct the array.
Use three pointers to keep track of the positions of 0s, 1s, and 2s.
One-pass solution: Maintain three indices (low, mid, high) and swap elements accordingly.

Deletion in min heap involves removing the root node and rearranging the heap to maintain the min heap property.
To delete the root node in a min heap, swap it with the last node in the heap.
Remove the last node and then heapify the heap starting from the root to maintain the min heap property.
Example: If the min heap is [10, 20, 30, 25, 40], after deletion the heap becomes [20, 25, 30, 40].

Severity, Priority, and Criticality are different aspects of issue management in software testing.
Severity refers to the impact of a defect on the system's functionality.
Priority indicates the order in which defects should be fixed based on business needs.
Criticality combines severity and priority to determine the overall importance of a defect.
For example, a defect causing a system crash would have high severity, high...
Equivalence partitioning is a software testing technique where input data is divided into partitions and only one value from each partition is tested.
Input data is divided into groups or partitions based on similar characteristics
One value from each partition is selected as a representative for testing
Helps in reducing the number of test cases while ensuring maximum coverage

Backward compatibility refers to the ability of a system to accept input intended for an older version of the system.
Allows newer versions of software to work with data or systems from older versions
Ensures that changes in the software do not break compatibility with existing data or systems
Helps in smooth transition and adoption of new versions without disrupting existing processes
A paradox in testing refers to a situation where a test case both passes and fails at the same time.
Paradox in testing can occur when a test case has conflicting requirements or conditions.
It can also happen when there are errors in the test setup or execution that lead to unexpected results.
For example, a test case may pass when run individually but fail when run as part of a test suite due to dependencies.
