80. Remove Duplicates from Sorted Array II

Leetcode Solutions

Initialize two pointers i and j to 1 and 0 respectively.
Initialize a variable count to 1 to keep track of the count of each unique element.
Iterate over the array starting from the second element.
If the current element is the same as the previous element, increment count.
If count is less than or equal to 2, copy the current element to the position at j and increment j.
If the current element is different from the previous element, reset count to 1 and copy the element to the position at j and increment j.
Continue this process until the end of the array is reached.
Return j as the new length of the array.
