This was fairly easy to figure out using while loops, but challenging using the modulo operator. To think that I almost quit at the DNA problem! Otherwise, move to next loop directly. Greedy best-first search: search algorithm that expands the node that is closest to the goal, as estimated by an heuristic function h(n). jjessie. Greedy algorithms find the overall, or globally, optimal solution for some optimization problems, but may find less-than-optimal solutions for some instances of other problems.". Think of a “greedy” cashier as one who wants to take the biggest bite out of this problem as possible with each coin they take out of the drawer. kicks off with an afternoon event called CS50 Puzzle Day. Harvard University. You need not try to check whether a user’s input is too large to fit in a float. Prompt user for change owed. cs50 pset4 recover.c need advice; CS50 PS 1 Greedy; cs50 list of languages used. As I learnt in the previous exercise, I wrote some pseudocode first to figure out the steps: Then, I declared the variables (having them at the top is not the best practice, but since the exercise was short and they would be visible, I decided to declare all of them before prompting the user for input). It turns out that this greedy approach (i.e., algorithm) is not only locally optimal but also globally so for America’s currency (and also the European Union’s). -0.41 How much change is owed? 1. Each fall, CS50 at Harvard (and Yale!) Greedy challenges us to figure out the least number of coins to return based on a dollar amount given by the user. zangiku / greedy.c.

Due to the inherent imprecision of floating-point values, we were advised to convert dollars to cents (from a float to an int) to avoid possible errors. But in every while loop for each cent type I wrote like (change >= 10) when it should've been (cents >= 10) so the rounding actually happens. Use get_float from the CS50 Library to get the user’s input and printf from the Standard I/O library to output your answer. Loop one: If input >= 25 or multiple -> then give x quarter coins and move to next loop. Sign in to view. 215 1 1 silver badge.

After all, how many cents does one dollar equal? credit.c # include < stdio.h > # include < cs50.h > # include < string.h ... mario.c, greedy.c But I'm still trying to understand how to proceed with credit.c. This is an very easy means to specifically get lead by on-line. Try printing its value to, say, 55 decimal places, with code like the below: And so, before making change, you’ll probably want to convert the user’s input entirely to cents (i.e., from a float to an int) to avoid tiny errors that might otherwise add up! Needless to say, another 25¢ bite would be too big (assuming the cashier prefers not to lose money), and so our greedy cashier would move on to a bite of size 10¢, leaving him or her with a 6¢ problem.

Convert dollar to cents, that is, float to int (multiply them by 100). The program should first prompt the user for input (in this case, how much change is owed), and configure some functions in c to determine the minimum amount of coins that could be used to give back the change. Using get_float alone will ensure that the user’s input is indeed a floating-point (or integral) value but not that it is non-negative. - duliodenis/harvard-cs50-psets A solution that has the lowest path cost among all solutions.
