Given a number such as 123 having digits 1,2 and 3.

Now Product of Number and its digits is = 123*1*2*3 = 768. Now 123 is the seed number for 768. You would be given a number and you have to identify whether any seed element exists for that number. for Ex: - 4977 has two such seed numbers 79 and 711. You have to print both.

The Mingo game:

The game of Mingo involves a 100 X 100 board with unique positive whole numbers in the range from 1 to 1,000,000 randomly distributed in the cells. Unique numbers are "called" one at a time and the goal is to have a "Mingo", which is an entire row or column of cells with numbers that have been called; one might also form a diagonal from corner to corner with numbers that have been called. Write a function that takes as parameters a square array of 100 X 100 positive whole numbers and list of "called" numbers. Your function will report whether a "Mingo" occurs, and after how many called numbers the first Mingo occurs. You may assume valid input.

Write a program to print the below series:

1 11 21 1211 111221 312211 13112221 ....

Another example of the series:

12 1112 3112 132112 1113122112 ....

You will be given a number. You will have to print the first ten numbers in the series. The series is basically the number of occurrence followed by the number. The occurrence should be continuous.

Given a certain range, produce all numbers in that range that fit the criteria. The criteria is as follows:

a number that starts with 2 of the same number, and then the sum of the previous 2 is that of the next number, and etc. For example:

112358, 121224, 448

If given a number find a number if it is colorful. A number is said to be colorful if all its possible unique permutations multiplication result different.

Eg: if n = 1234 then permutations are (1,2),(1,3),(1,4), (2,3),(2,4),(3,4),(1,2,3), (1,2,4), (2,3,4). That's it, no other combination. Find the multiplication of digits in each combination and if any of them repeats then number is not colorful.

The cows and bulls game, Player A chooses a word and player B guesses a word. You say bulls when a character in the player B's guess match with a character in player A's word and also it is in the corect position as in A's word. You say cows, when a character in the player B's word match the character in player A, but it is not in the correct position. The characters are case insensitive. Given two words player A's and player B's,Write a function that return the number of bulls and no of cows. For example,

A - Picture B- Epic, bulls -0, cows - 4

A - forum B - four, bulls - 3 cows - 1

Jumper Game: A NxN grid which contains either of 0-empty, 1 - player1, 2 - player 2. Given a position in the grid, find the longest jump path. For jump path, you can horizontally or vertically, you can jump on opponent cell and also the landing cell should be empty. No opponent cell can be jumped more than once. Write a function which takes grid and a specific position in the grid, and returns the longest possible number of jumps in the grid.

Colorful Number:

A number can be broken into different sub-sequence parts. Suppose, a number 3245 can be broken into parts like 3 2 4 5 32 24 45 324 245. And this number is a colorful number, since product of every digit of a sub-sequence are different. That is, 3 2 4 5 (3*2)=6 (2*4)=8 (4*5)=20 (3*2*4)= 24 (2*4*5)= 40

But 326 is not a colorful number as it generates 3 2 6 (3*2)=6 (2*6)=12.

You have to write a function that tells if the given number is a colorful number or not.

A string "aBIY" is said to be a well-ordered word as each of the letters are in sequential manner regardless of case. So, "AbLe" is not a well-ordered word.

You are a anti-hacker. you have a number of character sequences. Your task is to generate all possible well-ordered word that can be generated by those numbers of given character sequences.

Edge Detection:

Two-dimensional array representation of an image can also be represented by a one-dimensional array of W*H size, where W represent row and H represent column size and each cell represent pixel value of that image. you are also given a threshold X. For edge detection, you have to compute difference of a pixel value with each of it's adjacent pixel and find maximum of all differences. And finally compare if that maximum difference is greater than threshold X. if so, then that pixel is a edge pixel and have to display it.
