Today is my day 57th of #100dayofcode and #python. Today also continued to learned more properties of SQL including INNER JOIN,LEFT JOIN, RIGHT JOIN, FULL JOIN, IS LIKE, NOT LIKE, IS NULL, IS NOT NULL etc from Datacamp
Also tried to complete some assignment in coursera regarding to the topic algorithmic toolbox. I tired to solve money change problems, Fractional Knapsack problems, car fueling problem.
We are going to change Rs.28. In the shop shopkeeper has only Rs.1, Rs.5, Rs.10 as a change. So, possible change for 28 are 10,10,5,1,1,1. For this I tried to write following code.
number = 28 valid_changes = [1, 5, 10] rem = number changes= while rem!=0: # print(rem) if rem%valid_changes==0: changes.extend([valid_changes]) rem -= valid_changes elif rem%valid_changes==0: changes.extend([valid_changes]) rem -= valid_changes else: changes.extend() rem-=1 print(len(changes))
When above code is run we get,
28 27 26 25 20 10 [1, 1, 1, 5, 10, 10]
