1. Print Permutations - String
Easy
30m average time
80% success
0/40
Asked in companies
You are given an input string 'S'. Your task is to find and return all possible permutations of the input string.
Note:
1. The input string may contain the same characters, so there will also be the same permutations.
2. The order of permutation does not matter.
Problem approach
In our recursive function to find all permutations, we can use unordered_set for taking care of duplicate element remaining in the active string. While iterating over the elements of the string, we will check for that element in the unordered_set and if it found then we will skip that iteration or otherwise we will insert that element into unordered_set. As on an average all the unordered_set operations like insert() and find() are in O(1) time then the algorithm time complexity will not change by using unordered_set.
2. Find Minimum Number Of Coins
Easy

Asked in companies
Given an infinite supply of Indian currency i.e. [1, 2, 5, 10, 20, 50, 100, 500, 1000] valued coins and an amount 'N'.
Find the minimum coins needed to make the sum equal to 'N'. You have to return the list containing the value of coins required in decreasing order.
For Example
For Amount = 70, the minimum number of coins required is 2 i.e an Rs. 50 coin and a Rs. 20 coin.
Note
It is always possible to find the minimum number of coins for the given amount. So, the answer will always exist.
Problem approach
This problem is a simple variation of coin change problem. Here Greedy approach works as the given system is canonical
