Associate Software Engineer

You are given an array consisting of 'N' positive integers where each integer is either 0 or 1 or 2. Your task is to sort the given array in non-decreasing order.

Note :

1. The array consists of only 3 distinct integers 0, 1, 2.
2. The array is non-empty.

You are given an array of integers 'ARR' of length 'N' and an integer Target. Your task is to return all pairs of elements such that they add up to Target.

Note:

We cannot use the element at a given index twice.

Ninja has been given two sparse matrices ‘MAT1’ and ‘MAT2’ of integers having size ‘N’ x ‘M’ and ‘M’ x ‘P’, respectively.

A sparse matrix is a matrix that contains very few non-zero elements.

Ninja has to find the matrix formed by the multiplication of ‘MAT1’ and ‘MAT2’. As Ninja is busy with some other tasks so he needs your help. Can you help Ninja to find the matrix formed by the multiplication of ‘MAT1’ and ‘MAT2’?

Note: The number of columns in ‘MAT1’ i.e ‘M’ is equal to the number of rows in ‘MAT2’ i.e ‘M’. It means we can always multiply ‘MAT1’ with ‘MAT2’.

For example:

For the ‘MAT1’ and ‘MAT2’ given below, ‘MAT3’ is the matrix formed by multiplying ‘MAT1’ and ‘MAT2’. 

1. MAT3[0][0] = MAT1[0][0] * MAT2[0][0] + MAT1[0][1] * MAT2[1][0]  ie. 2 * 1 + 1 * 4 = 6
2. MAT3[1][0] = MAT1[1][0] * MAT2[1][0] + MAT1[1][1] * MAT2[1][0] ie. 0 * 6 + 0 * 4 = 0
