@neelmani98 hey ,here is recursive approach please try it:
Recursive approach :

  • If the start index reaches the length of the array, then return empty array
  • Else keep the first element of the array with yourself and pass the rest of the array to recursion.
    • If the element at start index is not equal to x then just simply return the answer which came from recursion.
    • Else if the element at start index is equal to x then shift the elements of the array (which is the answer of recursion) one step to the right and then put the start index in the front of the array (which came through recursion)
