Sum of Digits | FLOW006

Problem You're given an integer N . Write a program to calculate the sum of all the digits of N . Input Format The first line contains an integer T , the total number of testcases. Then follow T lines, each line contains an integer N . Output Format For each test case, calculate the sum of digits of N , and display it in a new line. Constraints 1 ≤ � ≤ 1000 1 ≤ T ≤ 1000 1 ≤ � ≤ 1000000 1 ≤ N ≤ 1000000 Sample 1: Input Output 3 12345 31203 2123 15 9 8 Solution: #include <bits/stdc++.h> using namespace std; int main() { int t; cin>>t; while(t--) { int n; cin>>n; int sum = 0; while(n!=0) { int r = n%10; sum+= r; ...

Valid Triangles | FLOW013

Problem Write a program to check whether a triangle is valid or not, when the three angles of the triangle are the inputs. A triangle is valid if the sum of all the three angles is equal to 180 degrees. Input Format The first line contains an integer T , the total number of testcases. Then T lines follow, each line contains three angles A , B and C , of the triangle separated by space. Output Format For each test case, display 'YES' if the triangle is valid, and 'NO', if it is not, in a new line. Constraints 1 ≤ T ≤ 1000 1 ≤ A,B,C ≤ 180 Sample 1: Input Output 3 40 40 100 45 45 90 180 1 1 YES YES NO Solution: #include <iostream> using namespace std; int main() { // your code goes here int t; cin>>t; while(t--){ int a,b,c; cin>>a>>b>>c; if((a+b+c)==180) cout<<"YES"; ...

Number Mirror | START01

Problem Write a program that takes a number N as the input, and prints it to the output. Input Format The only line contains a single integer. Output Format Output the answer in a single line. Constraints 0 ≤ � ≤ 1 0 5 0 ≤ N ≤ 1 0 5 Sample 1: Input Output 123 123 Sample 2: Input Output 15 15 Solution: #include <iostream> using namespace std; int main() { // your code goes here int n; cin>>n; cout<<n; return 0; }
