Step 1 Pseudo code to get the elements in two arrays with no duplicates

Pseudo code to get the elements in two arrays with no duplicates:

 

function findCommonElements(array1, array2):
    commonElements = []
    i = 0
    j = 0
    m = length of array1
    n = length of array2
    
    while i < m and j < n:
        if array1[i] == array2[j]:
            if commonElements is empty or last element of commonElements is not equal to array1[i]:
                add array1[i] to commonElements
            increment i and j
        else if array1[i] < array2[j]:
            increment i
        else:
            increment j
    
    resultArray = []
    for each element in commonElements:
        append the element to resultArray
    
    return resultArray

commonElements = findCommonElements(array1, array2)
print(commonElements)
