3. Write a program with which you can convert a human height given in feet and inches

to centimeters. The program should ask the user to type in his or her height in two

parts: first the height in feet and then the inches part for the height. (A person can

say that his or her height is, for example, 5 feet and 9 inches. That would be 30.48

* 5 + 2.54 * 9 centimeters.

There can be thus two separate input statements in the program. After the program

has received the feet and the inches, it should calculate the corresponding value in

centimeters and print it to the screen.

Write a program that reads lines of text and appends them to a char buffer[1000]. Stop after reading 1,000 characters. As you read in the text, replace all newline characters '\n' with '\0' terminators. Establish an array char* lines[100], so that the pointers in that array point to the beginnings of the lines in the text. Consider only 100 input lines if the input has more lines. Then display the lines in reverse order, starting with the last input line. 

#include<iostream>

using namespace std;

int main(){

double speed = 55;

double hours = 4;

double distance = 0;

double i = 0.5;

while(i<=hours){

distance = distance + (speed / 2);

cout<<i<<endl;

cout<<"Distance:  "<<distance<<endl;

i += 0.5;

}

}

You are given an integer N. For each integer i from 2 to N, assign a positive integer Ali] such that the following conditions hold:

•  For any pair of integers (i, j), if i and j are co-prime, then A[i]! = A[j].

•  The maximum value among all A[i] is the minimum possible.

Bob decided to go on a trip. There are total N kids on the trip. There are 3 types of toys - 'Type-I ', 'Type-2', and 'Type-3' available for distribution among N kids. Each of the kids is asked, what kind of toy he prefers from the current lot. If the kid does not like any toy from the current lot, then he or she would get a toy among the remaining types with equal probability.

You have given an array A containing N integers. You can do the following operation at most K times:

•  Choose any index i and increase the value of At by 1.

Your task is to find the maximum bitwise OR of the array.

Input format

•  The first line contains an integer T denoting the number of test cases.

•  The first line of each test case contains two space-separated integers N and K.

•  The second line of each test case contains N space-separated integers denoting array A.

Output format

For each test case, print the maximum possible bitwise OR of the array after performing at most K operations in a new line.

Constraints

1 ≤ T ≤ 100000 1 ≤ N ≤ 200000

O ≤ K ≤ le18

O ≤ Ai ≤ 2⁶⁰

It is guaranteed that the sum of N over T test cases does not exceed le6.

Explanation

For the first test case, we can increase the value of the 5-th index by 2. Thus the A becomes {1, 3, 7, 0, 8, 1}. The bitwise OR of array A becomes 15.

Population limit: 20792

Note: Population limit will change at random intervals. So please make sure answer is computed for the correct population limit before submitting.

A university's library has been having electricity issues and students have been struggling to study during nights.

Each light source can illuminate a circle with a radius of r, and there are n tables in the library and the i_th table is positioned at point (x_i, y_i). You have to help the university find the minimum number of light sources (k), such that each table is illuminated by at least 1 light source.

Input format

• The first line contains integers n and r respectively.

• In each of the next n lines, there are two integers representing x_i and y_i respectively that display the position of the ith table.

Output format

• In the first line of output, print an integer k that represents the number of light sources.

Odd even prime multiples

Humans have finally made contact with aliens from outer space who call themselves Primes. Naturally, each of their individuals loves prime numbers. Their emperor loves the prime number p the most. However, their maths is much more advanced than the version we use on Earth. They have very long numbers with several digits going up to 100 digits. A number is said to be valid for them if it follows the following conditions:

Task

The emperor has sent the message that he will consider humans an intelligent life form if you can tell him the number of valid numbers between L and R (both inclusive). Since the number of such numbers can be too large, you only need to tell the answer modulo (10⁹+7).
