#### Try First, Check Solution later

1. You should first read the question and watch the question video.
2. Think of a solution approach, then try and submit the question on editor tab.
3. We strongly advise you to watch the solution video for prescribed approach.

`1. You are given a number n1, representing the number of rows of 1st matrix.2. You are given a number m1, representing the number of columns of 1st matrix.3. You are given n1*m1 numbers, representing elements of 2d array a1.4. You are given a number n2, representing the number of rows of 2nd matrix.5. You are given a number m2, representing the number of columns of 2nd matrix.6. You are given n2*m2 numbers, representing elements of 2d array a2.7. If the two arrays representing two matrices of dimensions n1 * m1 and n2 * m2 can be multiplied, display the contents of prd array as specified in output Format.8. If the two arrays can't be multiplied, print "Invalid input".`
Input Format
`A number n1A number m1e11e12..e21e22.... n1 * m1 number of elements of array a1A number n2A number m2e11'e12'..e21'e22'.... n2 * m2 number of elements of array a2`
Output Format
`e11' e12' e13' ..e21' e22' e23' .... elements of prd array`
