Q1. Linklist search
Ans. 
Searching a linked list involves traversing nodes to find a specific value or element efficiently.
• A linked list consists of nodes, each containing data and a reference to the next node.

• To search, start from the head node and traverse until the desired value is found or the end is reached.

• Example: In a list 1 -> 2 -> 3, searching for '2' involves checking each node sequentially.

• Time complexity for searching in a l...read more

Q2. Sort in link List
Ans. 
Sorting in a linked list involves rearranging the elements in ascending or descending order based on a certain criteria.
• Use a sorting algorithm like bubble sort, selection sort, or merge sort to rearrange the elements in the linked list.

• Traverse the linked list and compare each element with the next one to determine the order in which they should be sorted.

• Update the pointers of the nodes in the linked list to reflect ...read more

Q2. Tell me factors affecting resistance of wire?
Ans. 
Factors affecting resistance of wire include material, length, cross-sectional area, and temperature.
• Material: Different materials have different resistivities, affecting resistance.

• Length: Longer wires have higher resistance due to increased collisions between electrons and atoms.

• Cross-sectional area: Thicker wires have lower resistance as there is more space for electrons to flow.

• Temperature: Resistance increases wit...read more
