Problem-Solving in C (Part-1): Loop and Array Operations(Recap)

A. Winter Sale

The winter sale began, and Mrs. Sarah wants to buy a T-shirt for her son. The T-shirt has a ticket that indicates a discount of X% and its price P after the discount. She now wants to know the price before the discount to know if the discount was worthy. Help her!

Input

Only one line containing two numbers X and P (1≤X≤99,1≤P≤4×10⁴) — the discount percentage, and the price of the T-shirt after the discount.

Output

Print the price of the T-shirt before the discount rounded up to two decimal places.

Examples

input

20 80

output

100.00

input

15 20

output

23.53

Answer:

#include<stdio.h>
#include<limits.h>
#include<string.h>
int main(){
    int x, a;
    scanf("%d %d", &x, &a);
    float sum= 1-(x/100.0);
    float price= a/sum;
    printf("%.2f\n", price);
    return 0;
}

B. Memo and Momo

Memo and Momo are playing a game. Memo will choose a positive number a, and Momo will choose a positive number b.

Your task is to tell them who will win according to the following rules:

• If both a and b are divisible by k, both of them win and you should print “Both”.
• If a is divisible by k but b isn’t, Memo wins and you should print “Memo”.
• If b is divisible by k but a isn’t, Momo wins and you should print “Momo”.
• If both a and b are not divisible by k, no one wins and you should print “No One”.

Input

Only one line containing three positive numbers a, b and k (1≤a,b,k≤10¹⁸).

Output

Print the answer as described in the statement.

Examples

input

15 7 3

output

Memo

input

22 10 2

output

Both

Answer:

#include<stdio.h>
#include<limits.h>
#include<string.h>
int main(){
    long long int a, b, k;
    scanf("%lld %lld %lld", &a, &b, &k);
    if(a%k==0 && b%k==0){
        printf("Both\n");
    }
    else if(a%k==0){
        printf("Memo\n");
    }
    else if(b%k==0){
        printf("Momo\n");
    }
    else{
        printf("No One\n");
    }
    return 0;
}

A. Square or rectangle

Given the width and the height of a shape determine whether it’s for a square or a rectangle?

Input

The first line contains a single integer t(1≤t≤1000)the number of test cases.

The first and only line of each test case contains two integers w,h(1≤w,h≤10⁶)representing the width and the height, respectively.

Output

For each test case print ‘Square’ if the shape is a square otherwise print ‘Rectangle’;

Example

input

3
10 10
13 200
300 300

output

Square
Rectangle
Square

#include<stdio.h>
#include<limits.h>
#include<string.h>
int main(){
    int test;
    scanf("%d", &test);
    for(int i=1; i<=test;i++){
    int width, height;
    scanf("%d %d", &width, &height);
    if(width==height){
        printf("Square\n");
    }
    else{
        printf("Rectangle\n");
    }
    }
    return 0;
}

1. A. Winter Sale (use float for this problem, ignore double as codeforces C compiler have problem with double data type)
2. B. Memo and Momo
3. A. Square or rectangle
