What is a code to count of quadruples with product of a pair equal to the product of the remaining pair and the other steps required given the following:
Count of quadruples with product of a pair equal to the product of the remaining pair | Function to count the number of unique quadruples from an array that satisfies the given condition.
Hashmap to store the product of pairs.
Store the count of required quadruples.
Traverse the array arr [ ] and generate all possible pairs.
Store their product.
Pair ( a , b ) can be used to generate 8 unique permutations with another pair ( c , d ).
Increment umap [ prod ] by 1.
Print the result.
