will design a function to help organize multiple meetings during a day. Each

meeting will have a start time and end time. Each meeting will need to reserve a private conference

room during that time. Your function will take all the meeting schedules and calculate the minimum

number of conference rooms you will need. Here are the requirements:

$1.$ The function will take the input as a sequence of lists, each list only contains two numbers, the

start time and the end time. For simplicity, we assume the time is just a float number in the

range of $0\mathrm{.}0$ to $24\mathrm{.}0.$ For example, the function may be given the following input:

findMinRooms$([1\mathrm{.}2,3\mathrm{.}4],[2\mathrm{.}3,5\mathrm{.}0],[3\mathrm{.}1,8\mathrm{.}0])$

Your code should return $3$ as the result, since during this time window $[3\mathrm{.}1,3\mathrm{.}4],$ all three

meetings will be going on in parallel. Another example:

findMinRooms$([1\mathrm{.}2,3\mathrm{.}4],[2\mathrm{.}3,5\mathrm{.}0],[4\mathrm{.}1,8\mathrm{.}0])$

this will return $2.$ Another example:

findMinRooms$([1\mathrm{.}2,3\mathrm{.}4],[2\mathrm{.}3,5\mathrm{.}0],[3\mathrm{.}1,8\mathrm{.}0],[1\mathrm{.}0,10\mathrm{.}0])$
