Q1. Is setup and hold uncertainty values are different
Ans. 
Yes, setup and hold uncertainty values are different in physical design engineering.
• Setup uncertainty is related to the arrival time of the data signal at the input of the flip-flop, while hold uncertainty is related to the removal time of the data signal.

• Setup time is the minimum amount of time the data input must be stable before the clock edge, while hold time is the minimum amount of time the data input must be sta...read more

Q1. I was asked to write two sum, palindrome function and merge sort code in whatever language I'm comfortable in
Add your answer
Q2. Two sum- return true or false
Ans. 
Given an array of integers, determine if there are two numbers that add up to a specific target.
• Iterate through the array and store each element in a hash set.

• For each element, check if the difference between the target and the element exists in the hash set.

• If the difference exists, return true; otherwise, continue iterating.

• Example: nums = [2, 7, 11, 15], target = 9. The function should return true as 2 + 7 = 9.
