Q5. Max sum subarray problem
Ans. 
Max sum subarray problem involves finding the subarray with the largest sum within an array.
• Iterate through the array and keep track of the current sum and maximum sum seen so far.

• Return the maximum sum found.

• Example: For array [-2, 1, -3, 4, -1, 2, 1, -5, 4], the max sum subarray is [4, -1, 2, 1] with sum 6.
