Answer 1

You can just do 2 nested for loops to compare each number in the array to every number after and if it finds a repeated value, remove it.

Answer 2

if you are trying to remove duplicates of one particular element:

start loop from 0

after left shift, next number(old i+1) is now on current position(i)
loop i++ causes you skip this number
so do correct possition for next number as i-- before next loop
and check it again

then you need only one for() and shift for() inside it
