The translation from the Berland language into the Birland language is not an easy task. Those languages are very similar: a berlandish word differs from a birlandish word with the same meaning a little: it is spelled (and pronounced) reversely. For example, a Berlandish word code corresponds to a Birlandish word edoc. However, it's easy to make a mistake during the «translation». Vasya translated word s from Berlandish into Birlandish as t. Help him: find out if he translated the word correctly.

Input

The first line contains word s, the second line contains word t. The words consist of lowercase Latin letters. The input data do not consist unnecessary spaces. The words are not empty and their lengths do not exceed 100 symbols.

Output

If the word t is a word s, written reversely, print YES, otherwise print NO.

Anton likes to play chess, and so does his friend Danik.

Once they have played n games in a row. For each game it's known who was the winner — Anton or Danik. None of the games ended with a tie.

Now Anton wonders, who won more games, he or Danik? Help him determine this.

Input

The first line of the input contains a single integer n (1 ≤ n ≤ 100 000) — the number of games played.

The second line contains a string s, consisting of n uppercase English letters 'A' and 'D' — the outcome of each of the games. The i-th character of the string is equal to 'A' if the Anton won the i-th game and 'D' if Danik won the i-th game.

Output

If Anton won more games than Danik, print "Anton" (without quotes) in the only line of the output.

If Danik won more games than Anton, print "Danik" (without quotes) in the only line of the output.

If Anton and Danik won the same number of games, print "Friendship" (without quotes).

You can not just take the file and send it. When Polycarp trying to send a file in the social network "Codehorses", he encountered an unexpected problem. If the name of the file contains three or more "x" (lowercase Latin letters "x") in a row, the system considers that the file content does not correspond to the social network topic. In this case, the file is not sent and an error message is displayed.

Determine the minimum number of characters to remove from the file name so after that the name does not contain "xxx" as a substring. Print 0 if the file name does not initially contain a forbidden substring "xxx".

You can delete characters in arbitrary positions (not necessarily consecutive). If you delete a character, then the length of a string is reduced by 11. For example, if you delete the character in the position 22 from the string "exxxii", then the resulting string is "exxii".

Input

The first line contains integer nn (3≤n≤100)(3≤n≤100) — the length of the file name.

The second line contains a string of length nn consisting of lowercase Latin letters only — the file name.

Output

Print the minimum number of characters to remove from the file name so after that the name does not contain "xxx" as a substring. If initially the file name dost not contain a forbidden substring "xxx", print 0.

The accompanying table shows a portion of data consisting of the selling price, the age, and the mileage for 20 used sedans.

a. Determine the sample regression equation that enables us to predict the price of a sedan on the basis of its age and mileage. (Negative values should be indicated by a minus sign. Round your answers to 2 decimal places.) [If you are using R to obtain the output, then first enter the following command at the prompt: options(scipen=10). This will ensure that the output is not in scientific notation.]

b. Interpret the slope coefficient of Age.

• The slope coefficient of Age is −528.13, which suggests that for every additional year of age, the predicted price of car decreases by $528.13.

• The slope coefficient of Age is −0.09, which suggests that for every additional year of age, the predicted price of car decreases by $0.09.

• The slope coefficient of Age is −528.13, which suggests that for every additional year of age, the predicted price of car decreases by $528.13, holding number of miles constant.

• The slope coefficient of Age is −0.09, which suggests that for every additional year of age, the predicted price of car decreases by $0.09, holding number of miles constant.

c. Predict the selling price of a seven-year-old sedan with 66,000 miles. (Round coefficient estimates to at least 4 decimal places and final answer to 2 decimal places.)

A barber shop offers haircuts to both students and faculty. Student demand for haircuts is given by pS(QS) = 24− 1QS. Faculty demand for haircuts is given by pF(QF) = 24− 1QF.

Students have more hair than professors (even the young professors), and longer hair costs more to cut. Reflecting this fact, the barber shop’s total costs are

C(QS,QF)=16QS +10QF
Suppose first that the barber shop can engage in perfect price discrimination.

1. (3 pts.) How many students get haircuts (Q∗S )? How many faculty get haircuts (Q∗F )? How much profit will the barber shop make?

2. (3 pts.) Under perfect price discrimination, is each of these statements true or false? Briefly explain your reasoning.

   i. Every faculty member with positive willingness to pay ends up getting a haircut. ii. Among the people who get haircuts, students pay more than faculty on average.

   iii. The cheapest haircut sold is sold to a faculty member

Now suppose that the barbershop cannot engage in personalized pricing. However, it is able to offer one price for students and a different price for faculty.

c. (3 pts.) Find the monopoly’s profit-maximizing prices p∗S and p∗F under group price discrimination. Which group is charged a bigger price markup?

Upset about discriminatory prices, student groups organize protests against the barber shop, using the catchy slogan “It’s unfair / to tax our hair!” The protests go viral, and the barber shop reluctantly agrees to charge everybody the same price, regardless of cost.

d. (3 pts.) Compute the market demand curve Q(p), then write the barber shop’s profits as a function of p. (Be careful with the costs!) What price will the barber shop charge?

For the following exercise, complete the calculations below. Evaluate different capital investment appraisal techniques by completing the calculations shown below:

Bongo Ltd. is considering the selection of one of two mutually exclusive projects. Both would involve purchasing machinery with an estimated useful life of 5 years.

Project 1 would generate annual cash flows (receipts fewer payments) of £200,000; the machinery would cost £556,000 with a scrap value of £56,000.

Project 2 would generate cash flows of £500,000 per annum; the machinery would cost £1,616,000 with a scrap value of £301,000.

Bongo uses straight-line depreciation. Its cost of capital is 15% per annum.

Assume that all cash flows arise on the anniversaries of the initial outlay, that there are no price changes over the project lives, and that accepting either project will have no impact on working capital requirements.

Assess the choice using the following methods by completing the calculations shown below:

ARR

NPV

IRR

Payback period

Calculate the missing answers:

ARR workings (Project 1)

These profits are the same each year in this question.

Annual depreciation (Cost - SV) / 5

Average NBV of investments
