Traversing in data structures or algorithms refers to visiting and processing each element in a data structure in a specific order.

• Traversing a binary tree involves visiting each node in a specific order such as in-order, pre-order, or post-order traversal.

• In array traversal, each element of the array is accessed and processed sequentially.

• Graph traversal algorithms like Depth First Search (DFS) and Breadth First Searc...read more

Level shifting is the process of changing the voltage level of a signal from one level to another.

• Level shifting is commonly used in electronics to ensure compatibility between different components or systems.

• It can involve using voltage level shifters or simple resistor networks.

• For example, shifting a 3.3V signal to a 5V signal for proper communication between devices.

The list count of ts refers to the number of occurrences of the letter 't' followed by the letter 's' in a given list.

• Count the number of times 'ts' appears in the list

• Ignore cases where 't' and 's' are not directly next to each other

• Example: ['cats', 'dogs', 'tsunami'] would have a list count of 1
