Write a basic program that performs simple file and mathematical operations.
a. Write a program that reads dates from input, one date per line. Each date's format must be as follows: March 1, 1990. Any date not following that format is incorrect and should be ignored. Use the find() method to parse the string and extract the date. The input ends with -1 on a line alone. Output each correct date as: 3/1/1990.
b. After the program is working as above, modify the program so that it reads all dates from an input file "inputDates.txt" (an Example file is attached).
c. Modify your program further so that after parsing all dates from the input file "inputDates.txt", it writes out the correct ones into an output file called: "parsedDates.txt".
Ex: If the input is:
March 1, 1990
April 2 1995
7/15/20
December 13, 2003
-1
then the output is:
3/1/1990

Algorithm:
Suppose we have n jobs with priority p1,…,pn and duration d1,…,dn as well as n machines with capacities c1,…,cn.
We want to find a bijection between jobs and machines. Now, we consider a job inefficiently paired, if the capacity of the machine its paired with is lower than the duration of the job itself.
We want to build an algorithm that finds such a bijection such that the sum of the priorities of jobs that are inefficiently paired is minimized.
The algorithm should be O(nlogn)
My ideas so far:
1. Sort machines by capacity O(nlogn)
2. Sort jobs by priority O(nlogn)
3. Going through the stack of jobs one by one (highest priority first): Use binary search (O(logn)) to find the machine with smallest capacity bigger than the jobs duration (if there is one). If there is none, assign the lowest capacity machine, therefore pairing the job inefficiently.
Now my problem is what data structure I can use to delete the machine capacity from the ordered list of capacities in O(logn) while preserving the order of capacities.
Your help would be much appreciated!
To solve the problem efficiently, you can use a min-heap data structure to store the machine capacities.
Here's the algorithm:Sort the jobs by priority in descending order using a comparison-based sorting algorithm, which takes O(nlogn) time.
Sort the machines by capacity in ascending order using a comparison-based sorting algorithm, which also takes O(nlogn) time.
Initialize an empty min-heap to store the machine capacities.
Iterate through the sorted jobs in descending order of priority:
Pop the smallest capacity machine from the min-heap.
If the machine's capacity is greater than or equal to the duration of the current job, pair the job with the machine.
Otherwise, pair the job with the machine having the lowest capacity, which results in an inefficient pairing.
Add the capacity of the inefficiently paired machine back to the min-heap.
Return the total sum of priorities for inefficiently paired jobs.
This algorithm has a time complexity of O(nlogn) since the sorting steps dominate the overall time complexity. The min-heap operations take O(logn) time, resulting in a concise and efficient solution.
