Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Jamie loves sleeping. One day, he decides that he needs to wake up at exactly hh: mm. However, he hates waking up, so he wants to make waking up less painful by setting the alarm at a lucky time. He will then press the snooze button every x minutes until hh: mm is reached, and only then he will wake up. He wants to know what is the smallest number of times he needs to press the snooze button.
A time is considered lucky if it contains a digit '7'. For example, 13: 07 and 17: 27 are lucky, while 00: 48 and 21: 34 are not lucky.
Note that it is not necessary that the time set for the alarm and the wake-up time are on the same day. It is guaranteed that there is a lucky time Jamie can set so that he can wake at hh: mm.
Formally, find the smallest possible non-negative integer y such that the time representation of the time x·y minutes before hh: mm contains the digit '7'.
Jamie uses 24-hours clock, so after 23: 59 comes 00: 00.
Input
The first line contains a single integer x (1 ≤ x ≤ 60).
The second line contains two two-digit integers, hh and mm (00 ≤ hh ≤ 23, 00 ≤ mm ≤ 59).
Output
Print the minimum number of times he needs to press the button.

In the second sample, Jamie can set his alarm at exactly at 01:07 which is lucky.

Revised
The current era, Heisei, will end on April 30, 2019, and a new era will begin the next day. The day after the last day of Heisei will be May 1, the first year of the new era.
In the system developed by the ACM-ICPC OB / OG Association (Japanese Alumni Group; JAG), the date uses the Japanese calendar (the Japanese calendar that expresses the year by the era name and the number of years following it). It is saved in the database in the format of "d days". Since this storage format cannot be changed, JAG saves the date expressed in the Japanese calendar in the database assuming that the era name does not change, and converts the date to the format using the correct era name at the time of output. It was to be.
Your job is to write a program that converts the dates stored in the JAG database to dates using the Heisei or new era. Since the new era has not been announced yet, we will use "?" To represent it.
Input
The input consists of multiple datasets. Each dataset is represented in the following format.
> g y m d
g is a character string representing the era name, and g = HEISEI holds. y, m, and d are integers that represent the year, month, and day, respectively. 1 ≤ y ≤ 100, 1 ≤ m ≤ 12, 1 ≤ d ≤ 31 holds.
Dates that do not exist in the Japanese calendar, such as February 30, are not given as a dataset. When converted correctly as the Japanese calendar, the date on which the era before Heisei must be used is not given as a data set.
The end of the input is represented by a line consisting of only one'#'. The number of datasets does not exceed 100.
Output
For each data set, separate the converted era, year, month, and day with a space and output it on one line. If the converted era is "Heisei", use "HEISEI" as the era, and if it is a new era, use "?".
Normally, the first year of the era is written as the first year, but in the output of this problem, ignore this rule and output 1 as the year.

Revised
The current era, Heisei, will end on April 30, 2019, and a new era will begin the next day. The day after the last day of Heisei will be May 1, the first year of the new era.
In the system developed by the ACM-ICPC OB / OG Association (Japanese Alumni Group; JAG), the date uses the Japanese calendar (the Japanese calendar that expresses the year by the era name and the number of years following it). It is saved in the database in the format of "d days". Since this storage format cannot be changed, JAG saves the date expressed in the Japanese calendar in the database assuming that the era name does not change, and converts the date to the format using the correct era name at the time of output. It was to be.
Your job is to write a program that converts the dates stored in the JAG database to dates using the Heisei or new era. Since the new era has not been announced yet, we will use "?" To represent it.
Input
The input consists of multiple datasets. Each dataset is represented in the following format.
> g y m d
g is a character string representing the era name, and g = HEISEI holds. y, m, and d are integers that represent the year, month, and day, respectively. 1 ≤ y ≤ 100, 1 ≤ m ≤ 12, 1 ≤ d ≤ 31 holds.
Dates that do not exist in the Japanese calendar, such as February 30, are not given as a dataset. When converted correctly as the Japanese calendar, the date on which the era before Heisei must be used is not given as a data set.
The end of the input is represented by a line consisting of only one'#'. The number of datasets does not exceed 100.
Output
For each data set, separate the converted era, year, month, and day with a space and output it on one line. If the converted era is "Heisei", use "HEISEI" as the era, and if it is a new era, use "?".
Normally, the first year of the era is written as the first year, but in the output of this problem, ignore this rule and output 1 as the year.

The current era, Heisei, will end on April 30, 2019, and a new era will begin the next day. The day after the last day of Heisei will be May 1, the first year of the new era.
In the system developed by the ACM-ICPC OB / OG Association (Japanese Alumni Group; JAG), the date uses the Japanese calendar (the Japanese calendar that expresses the year by the era name and the number of years following it). It is saved in the database in the format of "d days". Since this storage format cannot be changed, JAG saves the date expressed in the Japanese calendar in the database assuming that the era name does not change, and converts the date to the format using the correct era name at the time of output. It was to be.
Your job is to write a program that converts the dates stored in the JAG database to dates using the Heisei or new era. Since the new era has not been announced yet, we will use "?" To represent it.
Input
The input consists of multiple datasets. Each dataset is represented in the following format.
> g y m d
g is a character string representing the era name, and g = HEISEI holds. y, m, and d are integers that represent the year, month, and day, respectively. 1 ≤ y ≤ 100, 1 ≤ m ≤ 12, 1 ≤ d ≤ 31 holds.
Dates that do not exist in the Japanese calendar, such as February 30, are not given as a dataset. When converted correctly as the Japanese calendar, the date on which the era before Heisei must be used is not given as a data set.
The end of the input is represented by a line consisting of only one'#'. The number of datasets does not exceed 100.
Output
For each data set, separate the converted era, year, month, and day with a space and output it on one line. If the converted era is "Heisei", use "HEISEI" as the era, and if it is a new era, use "?".
Normally, the first year of the era is written as the first year, but in the output of this problem, ignore this rule and output 1 as the year.

Provide tags and a correct Python 3 solution for this coding contest problem.
On the planet Mars a year lasts exactly n days (there are no leap years on Mars). But Martians have the same weeks as earthlings — 5 work days and then 2 days off. Your task is to determine the minimum possible and the maximum possible number of days off per year on Mars.
Input
The first line of the input contains a positive integer n (1 ≤ n ≤ 1 000 000) — the number of days in a year on Mars.
Output
Print two integers — the minimum possible and the maximum possible number of days off per year on Mars.

Vasya has recently got a job as a cashier at a local store. His day at work is L minutes long. Vasya has already memorized n regular customers, the i-th of which comes after t_{i} minutes after the beginning of the day, and his service consumes l_{i} minutes. It is guaranteed that no customer will arrive while Vasya is servicing another customer.
Vasya is a bit lazy, so he likes taking smoke breaks for a minutes each. Those breaks may go one after another, but Vasya must be present at work during all the time periods he must serve regular customers, otherwise one of them may alert his boss. What is the maximum number of breaks Vasya can take during the day?
Input
The first line contains three integers n, L and a (0 ≤ n ≤ 10^{5}, 1 ≤ L ≤ 10^{9}, 1 ≤ a ≤ L).
The i-th of the next n lines contains two integers t_{i} and l_{i} (0 ≤ t_{i} ≤ L - 1, 1 ≤ l_{i} ≤ L). It is guaranteed that t_{i} + l_{i} ≤ t_{i + 1} and t_{n} + l_{n} ≤ L.
Output
Output one integer — the maximum number of breaks.

Vasya has recently got a job as a cashier at a local store. His day at work is L minutes long. Vasya has already memorized n regular customers, the i-th of which comes after t_{i} minutes after the beginning of the day, and his service consumes l_{i} minutes. It is guaranteed that no customer will arrive while Vasya is servicing another customer.
Vasya is a bit lazy, so he likes taking smoke breaks for a minutes each. Those breaks may go one after another, but Vasya must be present at work during all the time periods he must serve regular customers, otherwise one of them may alert his boss. What is the maximum number of breaks Vasya can take during the day?
Input
The first line contains three integers n, L and a (0 ≤ n ≤ 10^{5}, 1 ≤ L ≤ 10^{9}, 1 ≤ a ≤ L).
The i-th of the next n lines contains two integers t_{i} and l_{i} (0 ≤ t_{i} ≤ L - 1, 1 ≤ l_{i} ≤ L). It is guaranteed that t_{i} + l_{i} ≤ t_{i + 1} and t_{n} + l_{n} ≤ L.
Output
Output one integer — the maximum number of breaks.

Julia is going to cook a chicken in the kitchen of her dormitory. To save energy, the stove in the kitchen automatically turns off after k minutes after turning on.
During cooking, Julia goes to the kitchen every d minutes and turns on the stove if it is turned off. While the cooker is turned off, it stays warm. The stove switches on and off instantly.
It is known that the chicken needs t minutes to be cooked on the stove, if it is turned on, and 2t minutes, if it is turned off. You need to find out, how much time will Julia have to cook the chicken, if it is considered that the chicken is cooked evenly, with constant speed when the stove is turned on and at a constant speed when it is turned off.
Input
The single line contains three integers k, d and t (1 ≤ k, d, t ≤ 1018).
Output
Print a single number, the total time of cooking in minutes. The relative or absolute error must not exceed 10 - 9.
Namely, let's assume that your answer is x and the answer of the jury is y. The checker program will consider your answer correct if <image>.
Examples
Input
3 2 6
Output

Input
4 2 20
Output

Note
In the first example, the chicken will be cooked for 3 minutes on the turned on stove, after this it will be cooked for <image>. Then the chicken will be cooked for one minute on a turned off stove, it will be cooked for <image>. Thus, after four minutes the chicken will be cooked for <image>. Before the fifth minute Julia will turn on the stove and after 2.5 minutes the chicken will be ready <image>.
In the second example, when the stove is turned off, Julia will immediately turn it on, so the stove will always be turned on and the chicken will be cooked in 20 minutes.
