2244. Minimum Rounds to Complete All Tasks

Leetcode Solutions

Create a frequency map to count the occurrences of each difficulty level in the tasks array.
Initialize a variable minimumRounds to 0, which will store the minimum number of rounds needed.
Iterate over the frequency map:
- If any frequency is 1, return -1 as it's impossible to complete all tasks.
- If the frequency is divisible by 3, add frequency / 3 to minimumRounds.
- Otherwise, add frequency / 3 + 1 to minimumRounds to account for the remaining 1 or 2 tasks.
Return the value of minimumRounds.
