Question

To compare two arrays, we can use
a) Comparison operator ‘==’ directly on arrays
b) “switch case” statement
c) “for” loop
d) ternary operator on arrays

Answer 1

Answer:

"for" loop is the answer

Answer 2

Option (c) "for" loop is the correct answer.

• We can use a for loop to compare the given two arrays.
• Iterate in both of the arrays and compare if one element is present in the second array.

Example code (Python3):

$list1 = [1, 2, 3, 4, 5]\\list2 = [1, 2, 3, 7, 8]\\result = [ ]\\for\hspace{3}item\hspace{3}in\hspace{3}list1:\\\phantom{30}for\hspace{3}item1\hspace{3}in\hspace{3}list2:\\\phantom{1000}if\hspace{3}item == item1:\\\phantom{500000}result.append(item)\\print(result)$

Output:

$[1,2,3]$
