Razorpay Placement Papers 2024 - Actual Questions & Solutions

DSA Coding Problems (2024)

Question 1: Coin Change

Q1: You are given coins of different denominations and a total amount. Find the minimum number of coins needed to make up that amount.

Example:

Input: coins = [1,2,5], amount = 11
Output: 3

Solution (Java):

public int coinChange(int[] coins, int amount) {
    int[] dp = new int[amount + 1];
    Arrays.fill(dp, amount + 1);
    dp[0] = 0;

    for (int i = 1; i <= amount; i++) {
        for (int coin : coins) {
            if (coin <= i) {
                dp[i] = Math.min(dp[i], dp[i - coin] + 1);
            }
        }
    }

    return dp[amount] > amount ? -1 : dp[amount];
}

Time Complexity: O(amount × coins.length)
Space Complexity: O(amount)
