**World Record Codechef Solution:** Hello coders, today we are going to solve **World Record Codechef Solution**.

## Problem

**World Record Codechef Solution:** **“Usain Bolt makes a new world record completing 100100 m in 9.589.58 seconds”**.

This news headline has been echoing in Chef’s mind since 20092009 when he started his career in sprinting. This time in the 20212021 Tokyo Olympics he is determined to make a new world record.

There are mainly 33 important factors that result in the variation in speed during practice and during competition.

- The first factor is a difference in track material which results in variation in the speed at competition with respect to practice by a factor of k1k1.
- The second factor is wind speed which results in variation in the speed at competition with respect to practice by a factor of k2k2.
- The final factor is the maximum speed achieved during practice. If the maximum speed during practice is vv m/s then in competition it will be k3∗vk3∗v m/s.

Given Chef’s max speed vv during practice and the factors k1,k2,k3k1,k2,k3, find whether he will be able to create a new world record, i.e, can he complete 100100 m in less than 9.589.58 seconds?

**Note:** The final time displayed by the Olympics clock is showing after rounding the original time to 22 places of decimal and is the only measure of runners performance.

### Input:

- First line will contain TT, number of testcases. Then the testcases follow.
- Each testcase contains of a single line of input, four floats k1,k2,k3,vk1,k2,k3,v.

### Output:

Output in a single line, the answer, which should be “YES” if it’s possible for Chef to create a new world record and “NO” if not.

You may print each character of the string in uppercase or lowercase (for example, the strings “yEs”, “yes”, “Yes” and “YES” will all be treated as identical).

### Constraints

- 1≤T≤1051≤T≤105
- 0<k1,k2<20<k1,k2<2
- 0<k3≤10<k3≤1
- 9<v<119<v<11
- k1,k2,k3k1,k2,k3 contain 11 digit after decimal.
- vv contains 22 digits after decimal.

### Subtasks

**Subtask #1 (100 points):** original constraints

### Sample Input 1

3 1.0 1.0 1.0 10.45 1.0 1.0 1.0 10.44 1.0 1.0 0.9 10.44

### Sample Output 1

YES NO NO

### Explanation

**TestCase 1:** Final speed of Chef after considering all the factors will be 1∗1∗1∗10.45=10.451∗1∗1∗10.45=10.45 m / sec. So the time taken to complete the race will be 100/10.45=9.569=9.57100/10.45=9.569=9.57 sec after rounding to 22 places after decimal. Since the time is strictly less than the world record time, therefore Chef can break the record.

**TestCase 2:** Final speed of Chef after considering all the factors will be 1∗1∗1∗10.44=10.441∗1∗1∗10.44=10.44 m / sec. So the time taken to complete the race will be 100/10.44=9.578=9.58100/10.44=9.578=9.58 sec after rounding to 22 places after decimal. Since the time is equal to the world record time, therefore Chef can’t break the record.

**TestCase 3:** Final speed of Chef after considering all the factors will be 1∗1∗0.9∗10.44=9.3961∗1∗0.9∗10.44=9.396 m / sec. So the time taken to complete the race will be 100/9.396=10.643=10.64100/9.396=10.643=10.64 sec after rounding to 22 places after decimal. Since the time is strictly more than the world record time, therefore Chef can’t break the record.

## World Record- CodeChef Solution in JAVA

import java.util.Scanner; class cer { public static void main(String[] args) { Scanner sc = new Scanner(System.in); int test = sc.nextInt(); while(test-->0) { double k1=sc.nextFloat(); double k2=sc.nextFloat(); double k3=sc.nextFloat(); double v=sc.nextFloat(); double speed = k1*k2*k3*v ; double time = (100.00)/speed ; time = (double) Math.round(time*100)/100 ; //System.out.println(ans); if(time < 9.58) System.out.println("yes"); else System.out.println("no"); } } }

## World Record – CodeChef Solution in CPP

#include <bits/stdc++.h> using namespace std; int main() { int T; cin>>T; while(T--) { float k1,k2,k3,v; cin>>k1>>k2>>k3>>v; float ans=100.0/(k1*k2*k3*v); if(ans<9.575) cout<<"YES"<<endl; else cout<<"NO"<<endl; } return 0; }

## World Record CodeChef Solution in Python

T = int(input()) for i in range(T): k1,k2,k3,v = map(float,input().split()) a = round(100/(k1*k2*k3*v), 2) if a<9.58: print("YES") else: print("NO")
