Sum of N terms in Harmonic series:

Given integer N as input, write a program to display the sum of the first N terms in harmonic series. The series is: 1 + 1/2 + 1/3 + 1/4 + 1/5 ... + 1/N (N terms).

Input

The first line of input is an integer N.

Output

Print the sum rounded up to 2 decimal places.

Explanation

For

N = 5The sum of first 5 terms in harmonic series is 1 + 1/2 + 1/3 + 1/4 + 1/5

So, the output should be

2.28.

There is a structure called employee that holds information like employee code, name, date of joining. Write a program to create an array of the structure and enter some data into it. Then ask the user to enter current date. Display the names of those employees whose tenure is 3 or more than 3 years according to the given current date.

The game is played as follows:

The game consists of 3 turns, and the aim of the game is to score as many points as possible,Each turn begins with a roll of 6 standard dice,Matching dice (2 or more of the same number) can be set aside for points, and the remaining dice can then be re-rolled in an attempt to score more points 5s Points are “amount of dice * number on dice”, e.g. rolling three 5s is worth 15 points,The player chooses whether to set matching dice aside and whether to re-roll remaining dice, If the player chooses not to re-roll the dice, the points accumulated in the turn are added to their score and the turn ends, If no dice can be put aside after a roll, the player loses the points the potential points and the turn ends – hence, the player must decide how far to push their luck with additional rolls,The game involves quite a lot of luck, but there is also a small amount of strategy in choosing whether to set matching dice aside and whether to re-roll the remaining dice.

Two Words Combination

Given a sentence as input, print all the unique combinations of two words in lexicographical order.Input

The input will be a single line containing a sentence.Output

The output should be multiple lines, each line containing the unique combination of two words in lexicographical order.Explanation

For example, if the given sentence is "raju plays cricket", the possible unique combination of two are (cricket, plays), (cricket, raju), (plays, raju). So the output should be

cricket plays
cricket raju
plays raju

Sample Input 1

raju plays cricket

Sample Output 1

cricket plays

cricket raju

plays raju
