Python program to print all distinct elements of a given integer array.

Given an integer array. The elements of the array may be duplicate.Our task is to display the distinct values.

Example

Input::A=[1,2,3,4,2,3,5,6]
Output [1,2,3,4,5,6]

Algorithm

Step 1: input Array element.
Step 2:  Then pick all the elements one by one.
Step 3:  then check if the picked element is already displayed or not.
Step 4: use one flag variable which initialized by 0.if the element is displayed earlier flag variable is 1 and if the element is not displayed earlier flag variable is 0.
Step 5: Display distinct elements. 

Example Code

# Python program to print all distinct
# elements in a given array
def distinctelement(A, n1):
   print("Distinct Elements are ::>")
      for i in range(0, n1):
         c = 0
         for j in range(0, i):
            if (A[i] == A[j]):
               c = 1
               break
         if (c == 0):
            print(A[i])
# Driver code
A=list()
n1=int(input("Enter the size of the List ::"))
print("Enter the Element of List ::")
for i in range(int(n1)):
   k=int(input(""))
   A.append(k)
distinctelement(A, n1)

Output

Enter the size of the List ::4
Enter the Element of List ::
1
2
2
4
Distinct Elements are ::>
1
2
