This round was conducted on Myanatomy, and it had medium-level coding questions. It was 60 minutes long test.
1. Letter Combinations of a Phone Number
Moderate

Asked in companies
Given a string S containing digits from 2 to 9 inclusive. Your task is to find all possible letter combinations that the number could represent.
A mapping from Digits to Letters (just like in Nokia 1100) is shown below. Note that 1 does not map to any letter.
Problem approach
Step 1: Define a mapping of digits to letters, just like on a telephone keypad.
Step 2: Initialize an empty list to store the results.
Step 3: Define a recursive function, and generate combinations, that take the following parameters:
Digits: The remaining digits to process.combination: The current combination of letters.Inside the generate Combinations function:
-> Check if there are no more digits remaining (len(digits) == 0). If true, add the combination to the results list and return.
-> Get the letters corresponding to the first digit in the digits string.
Could you go through each letter and recursively call to generate Combinations with the remaining digits and the updated combination?
Step 5: Call the generateCombinations function initially with the input digits and an empty string as the initial combination.
Step 6: Return the list of results.
2. All Unique Permutations
Easy
15m average time
85% success
0/40
Asked in companies
You are given an array Arr consisting of N integers. Your task is to find all the unique permutations of the given array. For e.g if the array is {1, 1, 2}, the unique permutations of this array are {1, 1, 2}, {1, 2, 1}, {2, 1, 1}. Note that the total number of permutations of {1,1,2} is equal to 6 but out of those {1,1,2} and {1,2,1} occur twice.
Note:
1. There might be duplicates present in the array.
2. The order of the permutations in the output does not matter.
3. Do not use any kind of in-built library functions to find the answer.
