# How much time have I spent, end-to-end?

# 1h 30min

# How many submissions did it take to fully solve it?

# * Not counting basic tests submissions(more than 7)

# 1. My first BruteForce DFS+recursion was failing basic tests {recursion/memory limit}
# 2. For MinHeap solution it took me 2 submission.

# How much time have I spent, end-to-end?

# 2,5 hours to get an optimal working solution. 40 more minutes to make it clear and add comments

# What were the trickiest aspects? Where did you lose the most time?

# 1. Dealing with nested brackets
# 2. At first, started traversing the formula from the beginning. After coding a draft version, understood that handling nested brackets this way is tricky, so I changed the traverse direction
# 3. Later from test cases found out that:
#    - Element might consist of more than 2 characters
