Find pairs in an array with sum equal to 0.

• Use a hash table to store the frequency of each element.

• Iterate through the array and for each element, check if its complement (negative value) exists in the hash table.

• If it exists, add the frequency of the complement to the count of pairs.

• Return the count of pairs.

• Example: array = [2, -2, 3, 0, -3], pairs = 2 (-2, 2 and -3, 3)
