To find duplicate, use a hash set to store elements as you iterate through the array and check for duplicates.
To find largest and smallest elements, initialize variables with the first element and update them ...
To reverse an array of strings, iterate through the array and swap elements from start to end.
Iterate through the array using two pointers, one starting from the beginning and the other from the end.
Swap the elements at the two pointers and move the pointers towards the center until they meet or cross each other.
To find the median in 2 arrays of strings, merge the arrays, sort them, and then calculate the median.
Merge the two arrays into one array
