Dsa question
I applied via Company Website and was interviewed in Apr 2024. There were 2 interview rounds.
Find the length of the longest increasing subsequence in an array.
Use dynamic programming to solve this problem efficiently.
Iterate through the array and keep track of the longest increasing subsequence ending at each index.
Example: For array [10, 22, 9, 33, 21, 50, 41, 60, 80], the longest increasing subsequence is [10, 22, 33, 50, 60, 80] with length 6.
The question is asking about how to find the frequency of each character in a given string.
Iterate through the string and count the occurrences of each character
Store the counts in a data structure like a hashmap or array
Return the counts for each character
Reverse a given string
Create a new empty string to store the reversed string
Iterate through the original string from end to start and append each character to the new string
Return the reversed string
