Final answer:
The question involves finding the minimum cost for a company to rent cloud computing cores per day across multiple pricing plans, using dynamic programming.
Step-by-step explanation:
The question pertains to a scenario where a company plans to shift its infrastructure to the cloud. For this, they require renting k computing cores per day for n days and are evaluating m pricing plans. To calculate the minimum cost, one could write an algorithm that iterates through the days and selects the combination of plans that yields the lowest cost while meeting the core requirements each day. It would involve checking each plan's availability l[i] to r[i], the number of cores provided c[i], and the cost per core p[i]. This problem is a form of dynamic programming, where the function would return the accumulated minimum cost after processing all the plans while ensuring that the core requirements are met each day.
