Leetcode Solutions

Monotonic Stack Approach

  1. Initialize an empty stack and an array ans of the same length as nums with all elements set to 0.
  2. Iterate over the indices of nums from left to right.
    • While the stack is not empty and the current element is greater than the element at the index on the top of the stack, pop the stack.
    • Calculate the length of the subarray for the popped index and update ans.
    • Push the current index onto the stack.
  3. Clear the stack for the next iteration.
  4. Iterate over the indices of nums from right to left.
    • Repeat the same process as in step 2, but this time update the ans array by adding the length of the subarray to the right.
  5. Return the ans array.
