Input and Output C++
Problem Statement :
Objective
In this challenge, we practice reading input from stdin and printing output to stdout.
In C++, you can read a single whitespace-separated token of input using cin, and print output to stdout using cout. For example, let's say we declare the following variables:
string s;
int n;
and we want to use cin to read the input "High 5" from stdin. We can do this with the following code:
cin >> s >> n;
This reads the first word ("High") from stdin and saves it as string s , then reads the second word ("5") from stdin and saves it as integer n . If we want to print these values to stdout, separated by a space, we write the following code:
cout << s << " " << n << endl;
This code prints the contents of string s , a single space (" "), then the integer . We end our line of output with a newline using endl. This results in the following output:
High 5
Task Read 3 numbers from stdin and print their sum to stdout.
Input Format
One line that contains 3 space-separated integers: a , b , and c.
Constraints
1 < = a, b, c <= 1000
Output Format
Print the sum of the three numbers on a single line.
Solution :
Solution in C :
#include <cmath>
#include <cstdio>
#include <vector>
#include <iostream>
#include <algorithm>
using namespace std;
int main() {
/* Enter your code here. Read input from STDIN. Print output to STDOUT */
int a,b,c;
cin>>a>>b>>c;
cout<<a+b+c;
return 0;
}

Enter-View ( EV ) is a linear, street-like country. By linear, we mean all the cities of the country are placed on a single straight line - the x -axis. Thus every city's position can be defined by a single coordinate, xi, the distance from the left borderline of the country. You can treat all cities as single points. Unfortunately, the dictator of telecommunication of EV (Mr. S. Treat Jr.) do

A subsequence of a sequence is a sequence which is obtained by deleting zero or more elements from the sequence. You are given a sequence A in which every element is a pair of integers i.e A = [(a1, w1), (a2, w2),..., (aN, wN)]. For a subseqence B = [(b1, v1), (b2, v2), ...., (bM, vM)] of the given sequence : We call it increasing if for every i (1 <= i < M ) , bi < bi+1. Weight(B) =

A cricket match is going to be held. The field is represented by a 1D plane. A cricketer, Mr. X has N favorite shots. Each shot has a particular range. The range of the ith shot is from Ai to Bi. That means his favorite shot can be anywhere in this range. Each player on the opposite team can field only in a particular range. Player i can field from Ci to Di. You are given the N favorite shots of M

Consider a lowercase English alphabetic letter character denoted by c. A shift operation on some c turns it into the next letter in the alphabet. For example, and ,shift(a) = b , shift(e) = f, shift(z) = a . Given a zero-indexed string, s, of n lowercase letters, perform q queries on s where each query takes one of the following two forms: 1 i j t: All letters in the inclusive range from i t
