In this challenge, we will learn some basic concepts of C that will get you started with the language. You will need to use the same syntax to read input and write output in many C challenges. As you work through these problems, review the code stubs to learn about reading from stdin and writing to stdout.
This challenge requires you to print Hello, World! on a single line, and then print the already provided input string to stdout. If you are not familiar with C, you may want to read about the printf() command.
This challenge will help you to learn how to take a character, a string and a sentence as input in C.
To take a single character ch as input, you can use scanf("%c", &ch ); and printf("%c", ch) writes a character specified by the argument char to stdout.
char ch;
scanf("%c", &ch);
printf("%c", ch);
This piece of code prints the character ch.
You can take a string as input in C using scanf(“%s”, s). But, it accepts string only until it finds the first space.
In order to take a line as input, you can use scanf("%[^\n]%*c", s); where s is defined as char s[MAX_LEN]
where MAX_LEN is the maximum size of s. Here, [] is the scanset character. ^\n stands for taking input until a newline isn't
encountered. Then, with this %*c, it reads the newline character and here, the used * indicates that this newline character is discarded.
Note: The statement: scanf("%[^\n]%*c", s); will not work because the last statement will read a newline character, \n, from the previous line.
This can be handled in a variety of ways. One way is to use scanf("\n"); before the last statement.
You have to print the character, ch, in the first line. Then print s in next line. In the last line print the sentence, sen.
First, take a character, ch as input.
Then take the string, s as input.
Lastly, take the sentence sen as input.
Strings for s and sen will have fewer than 100 characters, including the newline.
Print three lines of output. The first line prints the character, ch.
The second line prints the string, s.
The third line prints the sentence, sen.
You are transporting some boxes through a tunnel, where each box is a parallelepiped, and is characterized by its length, width and
height. The height of the tunnel 41 feet and the width can be assumed to be infinite. A box can be carried through the tunnel only
if its height is strictly less than the tunnel's height. Find the volume of each box that can be successfully transported to the other
end of the tunnel. Note: Boxes cannot be rotated.
The first line contains a single integer n, denoting the number of boxes.
n lines follow with three integers on each separated by single spaces —
$1 \leq n \leq 100$ $1 \leq length_i, width_i, height_i \leq 100$
For every box from the input which has a height lesser than 41 feet, print its volume in a separate line.
You are given n triangles, specifically, their sides
The best way to calculate a area of a triangle with sides a, b, and c is Heron's formula:
The first line of each test file contains a single integer n. lines follow with three space-separated integers,
$1 \leq n \leq 100$ $1 \leq a_i, b_i, c_i \leq 70$ -
$a_i + b+i \gt c_i,a_i + c_i \gt b_i$ and$b_i + c_i \gt a_i$
We live in a big country. This country has towns towns_count in it.
Each town has some post offices in which packages are stored and transferred.
Post offices have different inner structure. Specifically, each of them has some limitations on the packages it can store - their weight should be between
min_weight and max_weight inclusively, where min_weight and max_weight are fixed for each office.
Packages are stored in some order in the office queue. That means, that they are processed using this order when sending and receiving.
Sometimes two post offices, even in different towns, may organize the following transaction: the first one sends all its packages to the second one. The second one accepts the packages that satisfy the weight condition for the second office and rejects all other ones. These rejected packages return to the first office back and are stored in the same order they were stored before they were sent. The accepted packages move to the tail of the second office's queue in the same order they were stored in the first office.
You should process several queries in your program. You'll be provided with structures package,
post_office and town. In order to complete this task, you should fill the following functions:
print_all_packages given the town t, print all packages in this town. They should be printed as follows:
Town_name:
0:
id_0
id_1
...
1:
id_2
id_3
...
...
where 0, 1 etc. are the numbers of post offices and 0th post office in the order of its queue, 1st one etc. There should be one '\t' symbol before post office numbers and two '\t'
symbols before the ids.
send_all_acceptable_packages - given the towns source and target and post office indices
source_office_index and target_office_index, manage the transaction described above between the
post office #source_office_index in town source and the post office #target_office_index in
town target.
town_with_most_packages - given all towns, find the one with the most number of packages in all
post offices altogether. If there are several of them, find the first one from the collection towns.
find_towns - given all towns and a string name, find the town with the name name.
It's guaranteed that the town exists.
First line of the input contains a single integer towns_count. towns_count blocks follow, each describing a town.
Every town block contains several lines. On the first line there is a string town_name - the name of the town.
On the second line there is an integer offices_count - the number of the offices in the town.
offices_count blocks follow then, each describing an office.
Every office block also contains several lines. On the first line there are three integers separated by single spaces:
packages_count (the number of packages in the office), min_weight and max_weight (described above).
packages_count blocks follow, each describing a package.
Every package block contains exactly two lines. On the first line there is a string id which is an id of the package.
On the second line there is an integer weight which is the weight of the package.
Then, there is a single integer queries on the line which is the number of queries.
queries blocks follow, each describing a query.
Every query block contains several lines. On the first line there is an integer 1, 2, or 3.
If this integer is 1, on the second line there is a string town_name - the name of town for which all packages should be
printed. If this integer is 2, on the second line there are string source_name, integer source_office_index, string
target_name and integer target_office_index separated by single spaces. That means transactions between post
office #source_office_index in the town source_name and post office #target_office_index in the town `target_name
should be processed.
If the integer is 3, no lines follow and the town with the most number of packages should be found.
- All integer are between
0and10. -
towns_count$\gt 0$ ,offices_count$\gt 0$ . - All strings have length
$\leq 5$ - All towns' names have only uppercase english letters and are unique.
- All packages' ids have only lowercase english letters and are unique.
- For each post office,
min_weight$\leq$ max_weight. - All queries are valid, that means, towns with the given names always exist, post offices with the given indices always exist.
For queries of type 1, print all packages in the format provided in the problem statement.
For queries of type 3, print "Town with the most number of packages is town_name" on a separate line.
