## Coin Change With Limited Coins Leetcode

**Coin Change With Limited Coins Leetcode**, The Coin Change with Limited Coins problem on LeetCode is a variation of the classic Coin Change problem. Unlike the original problem, this variation limits the number of coins available for use. This poses a new challenge, as the algorithm must now consider not only the value of the coins but also their availability. Ensuring that the number of coins used doesn’t exceed their limit is crucial. The solution to this problem can be achieved through dynamic programming, where we store the minimum number of coins required to reach each amount up to the target value. By using bottom-up iterative computation, we can efficiently calculate the minimum number of coins required for each value. Overall, the Coin Change with Limited Coins problem is an interesting twist on the classic Coin Change problem, and finding its optimal solution can be both challenging and rewarding.

## Coin Change Problem Example

**Coin Change Problem Example**, The coin change problem is a classic algorithmic question that deals with finding the minimum number of coins required to make change for a given amount. This problem is often used in interview settings to gauge a candidate’s problem-solving skills.

To solve this problem, we can leverage dynamic programming techniques. We start by creating an array that stores the minimum number of coins required for each value from 0 to the target amount. We then iterate through each denomination of coins and update the array accordingly.

By breaking the problem down into smaller subproblems and reusing solutions, dynamic programming allows us to efficiently solve the coin change problem. This approach is particularly useful when dealing with large amounts or a large number of denominations.

Overall, the coin change problem serves as a valuable exercise in algorithmic thinking and can be applied in a variety of real-world scenarios. Whether you’re a seasoned programmer or just starting out, this problem is a great way to improve your skills and deepen your understanding of dynamic programming.

## Coin Change 1

**Coin Change 1**, In the problem of Coin Change 1, we are given a set of coins with different denominations and a target amount to make change for. The goal is to find the minimum number of coins needed to make up the target amount. This problem can be solved using dynamic programming, specifically the bottom-up approach. To do this, we create a table that stores the minimum number of coins needed for each sub-target amount up to the target amount. We start by initializing the table with a value of infinity for all sub-target amounts, except 0. The value for 0 will be 0, since no coins are needed to make change for 0. We then iterate through the table, calculating the minimum number of coins needed for each sub-target amount based on the minimum values already stored in the table. At the end, the value stored in the table for the target amount will be the minimum number of coins needed to make change for that amount. This approach has a time complexity of O(N * V), where N is the number of coins and V is the target value. Overall, the Coin Change 1 problem is a classic example of dynamic programming that demonstrates the power of the bottom-up approach in solving complex problems efficiently.

## Coin Change Dynamic Programming

**Coin Change Dynamic Programming**, Dynamic programming is an effective technique for solving complex problems. The coin change problem is one such problem that can be solved using dynamic programming. In this problem, we are given a set of coins with different denominations and a target amount. The goal is to find the minimum number of coins required to make up the target amount. To solve this problem using dynamic programming, we first need to define the subproblems and the base case. The subproblem is to find the minimum number of coins required to make up a certain amount using a subset of the given coins. The base case is when the amount is zero, in which case we need zero coins. Once we have defined the subproblems and base case, we can use a recursive function to solve the problem. The function returns the minimum number of coins required to make up the target amount. We can then use memoization to store the results of the subproblems and avoid repeating the same calculations. In this way, we can solve the coin change problem using dynamic programming in an efficient and optimal manner.
