You are given a matrix ‘ARR’ having dimensions ‘N*M’. Your task to find the rank of the matrix ‘ARR’.

The rank of a matrix is defined as:

(a) The maximum number of linearly independent column vectors in the matrix.
OR
(b) The maximum number of linearly independent row vectors in the matrix.
Both definitions are equivalent.

Linear independence is defined as:

In the theory of vector spaces, a set of vectors is said to be linearly dependent if there is a nontrivial linear combination of the vectors that equals the zero vector. If no such linear combination exists, then the vectors are said to be linearly independent.

Asked in companies
SAP LabsMicrosoftPropTiger

For a given two strings, 'str1' and 'str2', check whether they are a permutation of each other or not.

Permutations of each other
Two strings are said to be a permutation of each other when either of the string's characters can be rearranged so that it becomes identical to the other one.

Example: 
str1= "sinrtg" 
str2 = "string"

The character of the first string(str1) can be rearranged to form str2 and hence we can say that the given strings are a permutation of each other.
