Implement a sorting algorithm for a continuous input data stream efficiently.
Use a min-heap or max-heap for efficient sorting of incoming data.
Consider using a streaming algorithm like Timsort for better performance.
Example: For input stream [5, 3, 8], output should be sorted as [3, 5, 8].
Maintain a buffer to store incoming data until it can be sorted.
Code to check if a given string is a palindrome or not.
Convert the string to lowercase to ignore case sensitivity.
Use two pointers, one at the start and one at the end of the string.
Compare the characters at both pointers and move them towards each other until they meet.
If all characters match, the string is a palindrome.
The internet is a global network of interconnected computers and servers that communicate with each other using standardized protocols.

Find unique character from a string and optimize it
Use a hash table to store the frequency of each character in the string
Iterate through the hash table to find the character with frequency 1
If there are multiple characters with frequency 1, return the first one
Optimization: Stop iterating through the hash table once a character with frequency 1 is found
