Computer Science, asked by mrmyselfsherlocked, 1 year ago

There are two banks; Bank A and Bank B. Their interest rates vary. You have received offers from both bank in terms of annual rate of interest, tenure and variations of rate of interest over the entire tenure.

You have to choose the offer which costs you least interest and reject the other.

Do the computation and make a wise choice.

The loan repayment happens at a monthly frequency and Equated Monthly Installment (EMI) is calculated using the formula given below :

EMI = loanAmount * monthlyInterestRate /

( 1 - 1 / (1 + monthlyInterestRate)^(numberOfYears * 12))

Constraints
1 <= P <= 1000000

1 <=T <= 50

1<= N1 <= 30

1<= N2 <= 30

Input Format
First line : P – principal (Loan Amount)

Second line : T – Total Tenure (in years).

Third Line : N1 is number of slabs of interest rates for a given period by Bank A. First slab starts from first year and second slab starts from end of first slab and so on.

Next N1 line will contain the interest rate and their period.

After N1 lines we will receive N2 viz. the number of slabs offered by second bank.

Next N2 lines are number of slabs of interest rates for a given period by Bank B. First slab starts from first year and second slab starts from end of first slab and so on.

The period and rate will be delimited by single white space.

Output
Your decision – either Bank A or Bank B.


Explanation
Example 1

Input

5 9.5

10 9.6

5 8.5

3

10 6.9

5 8.5

5 7.9

Output

Bank B

Example 2

Input

500000

26

13 9.5

3 6.9

10 5.6

3

14 8.5

6 7.4

6 9.6

Output

Bank B



My solution is this

//This is The Coding Area

#include
#include
#include
using namespace std;

int main()
{
float principal = 0.0,rate = 0.0,emi;
int n1,n2,t1,tenure;
float principal1 = 0.0,principal2=0.0;

cin>>principal;
cin>>tenure;
cin>>n1;


for(int i=0;i {
cout<<"\n";
cin>>t1>>rate;

rate=rate/(12*100);

emi= (principal*rate*pow(1+rate,t1))/(pow(1+rate,t1)-1);

principal1 += emi;
}

principal1+=principal;
//cout<
cin>>n2;

for(int i=0;i {
cout<<"\n";
cin>>t1>>rate;

rate=rate/(12*100);

emi= (principal*rate*pow(1+rate,t1))/(pow(1+rate,t1)-1);

principal2+= emi;
}

principal2+=principal;
//cout<
if(principal1>principal2)
{
cout<<"Bank B";
}
else
{
cout<<"Bank A";
}




}

it passes the public test cases though it gives wrong answer in private test cases.can anyone explain me what is the error in my code

mrmyselfsherlocked: thanks a lot!!
mrmyselfsherlocked: Actually its giving wrong answer for the first test case
mrmyselfsherlocked: it passes second test case the only problem here is the first test case

Hey there!

--------

Here's your code :

/* C++ Program

* Program by : Mahnaz */

#include <stdio.h>

#include <math.h>

#include <string.h>

#include <assert.h>

#include <limits.h>

#include <stdbool.h>

#include <stddef.h>

#include <stdint.h>

#include <stdlib.h>

int main()

{

long int p;

int t,n1,n2,i,j;

scanf("%ld%d%d%d",&p,&t,&n1,&n2);

int pea[n1],peb[n2];

float ra[n1],rb[n2],ai,bi,a = 0,b = 0;

for(i=0;i<n1;i++)

{

scanf("%d%lf",&pea[i],&ra[i]);

a = a+(p*pea[i]*ra[i]);

}

for(j=0;j<n2;j++)

{

scanf("%d%lf",&pea[i],&rb[i]);

b = b+(p*peb[j]*rb[j]);

}

ai = a/(100);

bi = b/(100);

if(ai<bi)

{

printf("Bank A");

}

else

{

printf("Bank B");

}

return 0;

}
