You have been given a grid containing some oranges. Each cell of this grid has one of the three integers values:

Value 0 - representing an empty cell.

Value 1 - representing a fresh orange.

Value 2 - representing a rotten orange.

Every second, any fresh orange that is adjacent(4-directionally) to a rotten orange becomes rotten.

Your task is to find out the minimum time after which no cell has a fresh orange. If it's impossible to rot all the fresh oranges then print -1.

Note:

1. The grid has 0-based indexing.
2. A rotten orange can affect the adjacent oranges 4 directionally i.e. Up, Down, Left, Right.

Given a string ‘STR’ which consists of uppercase and lowercase characters and spaces. Count the number of consonants in the string.

A consonant is an English alphabet character that is not vowel (a, e, i, o, and u). Examples of constants are b, c, d, f, etc.

Example :

Given string 'STR' : ‘Coding Ninjas’ there are 8 consonants i.e ‘C’,’d’,’n’,’g’,’N’,’n’,’j’,’s’, because these characters do not belong to set above mentioned set of vowels.
