You are given a string 'str' of length 'N'.

Your task is to reverse the original string word by word.

There can be multiple spaces between two words and there can be leading or trailing spaces but in the output reversed string you need to put a single space between two words, and your reversed string should not contain leading or trailing spaces.

Example :

If the given input string is "Welcome to Coding Ninjas", then you should return "Ninjas Coding to Welcome" as the reversed string has only a single space between two words and there is no leading or trailing space.

Create a function that determines whether a given number N belongs to the Fibonacci sequence. If N is found in the Fibonacci sequence, the function should return true; otherwise, it should return false.

You are given an array 'ARR' of the 'N' element. Your task is to find the maximum difference between any of the two elements from 'ARR'.

If the maximum difference is even print “EVEN” without quotes. If the maximum difference is odd print “ODD” without quotes.

For example:

Given 'ARR' = [1, 10, 5, 2, 8, 1 ] , answer is "ODD".
Here the maximum difference is between 10 and 1, 10 - 1 = 9

You are given a number N. You need to find the remainder when N is divided by 11.

Note :

Number N may be very large.

Selection sort is one of the sorting algorithms that works by repeatedly finding the minimum element from the unsorted part of the array and putting it at the beginning of the unsorted region of the array.

You are given an unsorted array consisting of N non-negative integers. Your task is to sort the array in non-decreasing order using the Selection Sort algorithm.

For Example:

Selection Sort implementation for the given array:  {29,72,98,13,87,66,52,51,36} is shown below :-

Given a string, determine if it is a palindrome, considering only alphanumeric characters.

Palindrome

A palindrome is a word, number, phrase, or other sequences of characters which read the same backwards and forwards.

Example:

If the input string happens to be, "malayalam" then as we see that this word can be read the same as forward and backwards, it is said to be a valid palindrome.

The expected output for this example will print, 'true'.

From that being said, you are required to return a boolean value from the function that has been asked to implement.

Print the following pattern

Pattern for N = 4

Hint

As taught in the video, you just have to modify the code so that instead of printing numbers, it should output stars ('*').

The dots represent spaces.

What experience do you have that would be relevant to this role?

What do you know about our company’s product/services?

Write a program to count and print the total number of characters (lowercase english alphabets only), digits (0 to 9) and white spaces (single space, tab i.e. '\t' and newline i.e. '\n') entered till '$'.

That is, input will be a stream of characters and you need to consider all the characters which are entered till '$'.

Print count of characters, count of digits and count of white spaces respectively (separated by space).
