Q3. Find number of Perfect subarrays of the given array .A perfects subarray has odd value at odd place and even value at even position.
Ans. 
Count the number of perfect subarrays in an array where odd values are at odd positions and even values are at even positions.
• Iterate through the array and keep track of the count of odd and even numbers encountered so far.

• If the count of odd and even numbers at the current index matches the index itself, increment the count of perfect subarrays.

• Example: For array [2, 1, 3, 4], there are 3 perfect subarrays: [2, 1], [1

Q3. You are given parallel bars selecting two bars you can make a container .Maximise area.Find the slution in o(n)
Ans. 
To maximize the area of a container formed by two parallel bars, use the two-pointer approach in O(n) time complexity.
• Use the two-pointer approach to iterate from both ends towards the center of the array.

• Calculate the area formed by the two bars at each step and update the maximum area found so far.

• Move the pointer with the smaller height towards the center to potentially find a larger area.

• Repeat the process until th
