Print Pretty C++
Problem Statement :
Given a text file with many lines of numbers to format and print, for each row of 3 space-separated doubles, format and print the numbers using the specifications in the Output Format section below. Input Format The first line contains an integer, T , the number of test cases. Each of the T subsequent lines describes a test case as 3 space-separated floating-point numbers: A , B and C, respectively. Constraints 1 <= T <= 1000 Each number will fit into a double. Output Format For each test case, print 3 lines containing the formatted ,A , B and C , respectively. Each A, B and C must be formatted as follows: 1 A: Strip its decimal (i.e., truncate it) and print its hexadecimal representation (including the 0x prefix) in lower case letters. 2 B: Print it to a scale of 2 decimal places, preceded by a + or - sign (indicating if it's positive or negative), right justified, and left-padded with underscores so that the printed result is exactly 15 characters wide. 3 C: Print it to a scale of exactly nine decimal places, expressed in scientific notation using upper case.
Solution :
Solution in C :
/* Enter your code here */
typedef long long llint;
llint AA = llint(A);
printf("0x%llx\n", AA);
char tmp[100];
sprintf(tmp, "%s%.2f", B >= 0? "+": "-", B);
string sb(tmp);
for (int i = 0; i + sb.size() < 15; i++) {
printf("_");
}
puts(tmp);
printf("%.9E\n", C);

Treeland is a country with n cities and n - 1 roads. There is exactly one path between any two cities. The ruler of Treeland wants to implement a self-driving bus system and asks tree-loving Alex to plan the bus routes. Alex decides that each route must contain a subset of connected cities; a subset of cities is connected if the following two conditions are true: There is a path between ever

You are given an unrooted tree of n nodes numbered from 1 to n . Each node i has a color, ci. Let d( i , j ) be the number of different colors in the path between node i and node j. For each node i, calculate the value of sum, defined as follows: Your task is to print the value of sumi for each node 1 <= i <= n. Input Format The first line contains a single integer, n, denoti

Shashank loves trees and math. He has a rooted tree, T , consisting of N nodes uniquely labeled with integers in the inclusive range [1 , N ]. The node labeled as 1 is the root node of tree , and each node in is associated with some positive integer value (all values are initially ). Let's define Fk as the Kth Fibonacci number. Shashank wants to perform 22 types of operations over his tree, T
