Witryna11 kwi 2024 · Naive Approach: The simplest approach is to try all possible combinations of given denominations such that in each combination, the sum of coins is equal to X. From these combinations, choose the one having the minimum number of coins and print it. If the sum any combinations is not equal to X, print -1 . Efficient Approach: The … Witryna3 lip 2024 · Problem Statement. You have a total of n coins that you want to form in a staircase shape, where every k-th row must have exactly k coins. Given n, find the total number of full staircase rows that can be formed. Constraints:- n is a non-negative integer and fits within the range of a 32-bit signed integer.

maximum number of coins you can get leetcode 1561 - YouTube

WitrynaThe maximum number of coins which you can have are: 7 + 2 = 9. On the other hand if we choose this arrangement (1, 2, 8), (2, 4, 7) you only get 2 + 4 = 6 coins which is not optimal. Example 2:Input: piles = [2,4,5]Output: 4Example 3:Input: piles = [9,8,7,6,5,1,2,3,4]Output: 18 Constraints: * 3 <= piles.length <= 105 * piles.

Witryna24 wrz 2024 · Since the minimum number of coins needed to make 6 is 3 (2 + 2 + 2), the new minimum number of ways to make 8 is by putting a 2-coin on top of the amount 6, thus making it 4 coins. Now that we’ve finished looking at the minimum number of coins needed to make each amount using 1-coins and 2-coins, let’s look at 5-coins: WitrynaThe topic is very good: Given the denomination of some coins, and find the minimum amount of coins that can be used in a given amount. Solution Idea: Because each coin can use unlimited number of times, this question is essentially a complete backpack problem. You can directly show the two-dimensional space compression as a one … Witryna17 kwi 2014 · Suppose I am asked to find the minimum number of coins you can find for a particular sum. That is, say, coins are 1, 3, 5, the sum is 10, so the answer should be 2, since I can use the coin 5 twice.
