Python Program to Print uncommon elements from two sorted arrays
Given two sorted arrays of distinct elements, we need to print those elements from both arrays that are not common. The output should be printed in sorted order.
Examples :
Input : arr1[] = {10, 20, 30}
arr2[] = {20, 25, 30, 40, 50}
Output : 10 25 40 50
We do not print 20 and 30 as these
elements are present in both arrays.
Input : arr1[] = {10, 20, 30}
arr2[] = {40, 50}
Output : 10 20 30 40 50
The idea is based on merge process of merge sort. We traverse both arrays and skip common elements.
Python3
# Python 3 program to find uncommon# elements of two sorted arrays def printUncommon(arr1, arr2, n1, n2) : i = 0 j = 0 k = 0 while (i < n1 and j < n2) : # If not common, print smaller if (arr1[i] < arr2[j]) : print( arr1[i] , end= " ") i = i + 1 k = k + 1 elif (arr2[j] < arr1[i]) : print( arr2[j] , end= " ") k = k + 1 j = j + 1 # Skip common element else : i = i + 1 j = j + 1 # printing remaining elements while (i < n1) : print( arr1[i] , end= " ") i = i + 1 k = k + 1 while (j < n2) : print( arr2[j] , end= " ") j = j + 1 k = k + 1 # Driver codearr1 = [10, 20, 30]arr2 = [20, 25, 30, 40, 50] n1 = len(arr1)n2 = len(arr2) printUncommon(arr1, arr2, n1, n2) # This code is contributed# by Nikita Tiwari. |
Output :
10 25 40 50
