This could be one way of doing it:
def find_missing(arr1, arr2):
# Set longer array to lst1, shorter to lst2
if len(arr1) > len(arr2):
lst1 = arr1
lst2 = arr2
else:
lst1 = arr2
lst2 = arr1
# Go through elements in longer list
for element in lst1:
# If this element is not in lst2, we found it, return result
if element not in lst2:
return element
0
solved IndexError: list index out of range – for i in arr1 and arr2 [duplicate]
