Check if two arrays are equal or not Python

PROGRAM TO CHECK IF TWO ARRAYS ARE EQUAL OR NOT

Two arrays are said to be equal if both of them contain the same set of elements, arrangements (or permutation) of elements may be different though.
Note: If there are repetitions, then counts of repeated elements must also be the same for two arrays to be equal. 




# Returns true if arr1[0..n-1] and

# arr2[0..m-1] contain same elements.

 

def areEqual(arr1, arr2, n, m):

 

    # If lengths of array are not

    # equal means array are not equal

    if (n != m):

        return False

    b1 = arr1[0]

    b2 = arr2[0]

     

    # find xor of all elements

    for i in range(1, n - 1):

        b1 ^= arr1[i]

 

    for i in range(1, m - 1):

        b2 ^= arr2[i]

 

    all_xor = b1 ^ b2

     

    # If all elements were same then xor will be zero

    if(all_xor == 0):

        return True

 

    return False

 

 

# Driver Code

arr1 = [3, 5, 2, 5, 2]

arr2 = [2, 3, 5, 5, 2]

n = len(arr1)

m = len(arr2)

 

# Function call

if (areEqual(arr1, arr2, n, m)):

    print("Yes")

else:

    print("No")







OUTPUT

Yes
