You don't need to read input or print anything. Your task is to complete the function polyMultiply() which takes the array Arr1 and Arr2and their size M and Nas input parameters and returns the polynomial in form of array formed after multiplication of given polynomials..
Expected Time Complexity: O(M*N) Expected Auxiliary Space: O(M*N)
1 ≤ M, N ≤ 100
1 ≤ Arr1[i] , Arr2[i] ≤ 100
