Q1. 
Reverse Only Letters Problem Statement
You are given a string S. The task is to reverse the letters of the string while keeping non-alphabet characters in their original position.
Example:
Input:
S = "...read more
Ans. Two Pointer Approach
Approach: Just like in order to reverse a string ‘S’ = “abcd”, we can can swap(S[0], S[3]) and swap(S[1],S[2]) to get new string “dcba”.
 
Similarly in this problem, we do the same using two pointers while ignoring the non-letter characters.
 
Eg: S = “a-bcd” we swap(S[0], S[4]) and swap(S[2], S[3]) to get the result.

Q2. 
Find Duplicates in an Array
Given an array ARR of size 'N', where each integer is in the range from 0 to N - 1, identify all elements that appear more than once.
Return the duplicate elements in any orde...read more
Ans. Sorting
1. The most trivial approach would be to sort the array/list ‘ARR’ and then return the duplicates.
2. After sorting the array in non-decreasing order, do the following for all the elements from i = 0 to i = n - 2:
   • If ARR[i] == ARR[i + 1], then add ARR[i] to the the output list.
   • While ARR[i] == ARR[i + 1], do i = i + 1, since we don’t want to add the same duplicate elements again and again.
   • Else continue.
3. After this loop, w...read more

Ans. Pancake Sorting.
The main idea to solve this problem is that if we want to place a number at an index, then we need a maximum of 2 moves that are:- 
 
1. Bring it to the 0th index by reversing the prefix array till its index, e.g., if you chose some index K, then reverse the array from 0th index till Kth index.
2. Reverse the prefix array from the 0th index to the index where we want to place it.

Sum of Digits Problem Statement

Ans. Brute Force Approach
The main idea is to do the sum of digits until it becomes less than 10.
 
Algorithm:
• Add a condition if N is less than 10 then return N.
• Do the sum of all digits.
• Make a recursive call and pass the sum of digits as N.
• Return the answer which you get from a recursive call.

Fibonacci Number Verification

Ans. Brute Force
The basic idea is to keep generating Fibonacci numbers until we find a number equal to the given number or the generated number becomes greater than the given number. If the generated number is equal to the given number then it means the given number is a Fibonacci number. Otherwise, it is not a Fibonacci number.
 
The steps are as follows:
 
1. Check if ‘N’ is 0 or 1, return true.
2. Create two variables ‘a’...read more

Q1. 
Character Frequency Problem Statement
You are given a string 'S' of length 'N'. Your task is to find the frequency of each character from 'a' to 'z' in the string.
Example:
Input:
S : abcdg
Output:
1...read more
Ans. Count Frequency
Since there are just 26 lower case characters, we can use an array of size 26 to store the result.
 
Here is the algorithm : 
 
1. Create an array (say, ‘FREQ’), where 0-th index stores the frequency of ‘a’, 1st index stores the frequency of ‘b’ and so on. So the last index i.e. 25th index stores the frequency of ‘z’.
2. Run a for loop from 0 to ‘N’ - 1 (say, iterator ‘i’), on the string and do the f...read more
