Last active January 26, 2021 21:51
Write a program which takes an Sorted Array and removes duplicates
// Write a program which takes an Sorted Array [ 1,2,3,4,6,6,6,7,8,99,99,99,1000]
// and removed duplicates. http://share.linqpad.net/sbrxsw.linq
// IDEA :: The idea here is to push the elements to the Left, so that all the unique elements are to the left of the array.
// When the elements dont match, you swap the places with the last unique element.
// When they match just move to next element.
void Main()
{
// [i/p] : [1,1,1,1] [o/p] : [1,1,1,1] and n=1
// [i/p] : [0] [o/p] : [0] and n=1
