What is the problem in my code? I got wrong answer. Please help.

Code: Select all

#include <iostream>
#include <stdlib.h>
#include <stdio.h>
#include <math.h>

using namespace std;

int main()
{
    int n, fpn, spn;
    string s;
    cin >> n;
    getchar();
    for (int i=0; i<n; i++){
        getline(cin, s, '-');
        fpn = (s[0]-65)*52+(s[1]-65)*26+(s[2]-65);
        getline(cin, s, '\n');
        spn = atoi(s.c_str());
        if (abs(fpn-spn)<=100)
            cout << "nice" << endl;
        else
            cout << "not nice" << endl;
        //cout << fpn << " " << spn << endl;
    }
    return 0;
}

How about at least trying the test cases posted right above your post and seeing what happens?

It's probably not a good idea to use a single "getchar" after using a "cin" and expect that to be a newline. Something like this is mostly a better bet

Code: Select all

/* Read in the number of plates */
scanf("%d", &numberOfPlates);

@v1n1t...For your given testcase the following output is shown:

Please use code tags when sharing input / output. It makes things easier to read.

I think your answer is wrong. Because BBZ = 103 and abs(103,627)=524>100. So I think it is "not nice".

Next, BBZ does not equal 103. Read the problem statement more carefully.

Here's a hint: What does the binary number

1011

equal in decimal? How do you proceed to expand it out? Try applying those same principals to this problem - except bear in mind that you're now in Base 26 - not Base 2.

@v1n1t...
Code AC. I am new in UVa OJ Board. For that reason did that kind of mistake.
