Minimum operations to make product of adjacent element pair of prefix sum negative | Function to find minimum operations needed to make the product of any two adjacent elements in prefix sum array negative.
Stores the minimum operations.
Stores the prefix sum and number of operations.
Traverse the array.
Update the value of sum.
Check if i + r is odd.
Check if prefix sum is not positive.
Update the value of ans and sum.
Check if prefix sum is not negative.
Update the value of ans and sum.
Update the value of res.
Print the value of res.
