10424 - Love Calculator

[rodriwan]

what am I doing wrong?

Thought a lot and cant see what is the problem with this code...

[c]
#include <stdio.h>
#include <ctype.h>

#define MAX(x, y) ( (x) > (y) ) ? (x) : (y)
#define MIN(x, y) ( (x) < (y) ) ? (x) : (y)

int
main(void)
{
int r1, r2, sum, i;
float res, min, max;
char str1[256], str2[256], c;

while (fgets(str1, 256, stdin) &&
fgets(str2, 256, stdin)) {
r1 = r2 = 0;
for (i = 0; str1[i]; ++i) {
c = tolower(str1[i]);
if (c >= 'a' && c <= 'z')
r1 += (c - 'a'+1);
}

for (i = 0; str2[i]; ++i) {
c = tolower(str2[i]);
if (c >= 'a' && c <= 'z')
r2 += (c - 'a'+1);
}

while (r1 > 9) {
sum = 0;
while (r1 > 0) {
sum += r1%10;
r1 /= 10;
}
r1 = sum;
}

while (r2 > 9) {
sum = 0;
while (r2 > 0) {
sum += r2%10;
r2 /= 10;
}
r2 = sum;
}

min = (float) MIN(r1, r2);
max = (float) MAX(r1, r2);

res = 100.0 * (min / max);
printf("%.2f\n", res);
}

return 0;
}
[/c]

thanks

If max = min = 0, then what value printed?

I think that there is a trap.

[b]I think this program is correct but judge reply wrong ans.anyone help me?

#include<stdio.h>

int x[26],l=0,l1=0;
for(int i=0;i<26;i++)

Hai guy,
I didn't analyze ur code but I also suffered much with this problem.
I think you should be conscious abt taking input. And you have to
check the condition fulfilled (I did mistake on proble specification).

I am not sure abt ur mistake.
Thanks.

If both values are zero simply output an empty line.
I got AC that way.

[minskcity]

My code is basicly the same as rodriwan's... And I'm getting WA too, even after printing a new line in case n1 = n2 = 0. Is there any other tricky inputs???
[cpp]#include <iostream>
#include <string>
#include <ctype.h>
using namespace std;

string s;
long n1, n2, h;

int main(){

while(getline(cin, s)){
n1 = n2 = 0;
for(unsigned long i = 0; i < s.size(); i++) s[i] = tolower(s[i]);
for(unsigned long i = 0; i < s.size(); i++)
if(s[i] >= 'a' && s[i] <= 'z') n1 += s[i] - 'a' + 1;
while(n1 > 10){
h = 0;
while(n1){
h += n1%10;
n1 /= 10;
}
n1 = h;
}

getline(cin, s);
for(unsigned long i = 0; i < s.size(); i++) s[i] = tolower(s[i]);
for(unsigned long i = 0; i < s.size(); i++)
if(s[i] >= 'a' && s[i] <= 'z') n2 += s[i] - 'a' + 1;
while(n2 > 10){
h = 0;
while(n2){
h += n2%10;
n2 /= 10;
}
n2 = h;
}

cout.setf(ios::fixed);
cout.precision(2);
if(!(n1 + n2)) cout << endl;
else if(n1 < n2) cout << 100*((double)n1)/((double)n2) << " %\n";
else cout << 100*((double)n2)/((double)n1) << " %\n";

}

return 0;
}

Hi, everyone, I'm getting furious with this problem (10424) Love Calculation.


Why do I get wrong answer??

When both sums are 0, i output an empty new line.
and I put the right value, otherwise.

I would like to know, if there is any problem with the input (blank lines,...etc)

If someone can help me with this "very simple" problem, I'll apreciate??

Thank you~

What happened to my code that gets WA....

while (cin>>p>>h)
{
int l=0,i=0;
for (int y=0;y<p.length();y++)
if ((p[y]-'A'>=0)&&(p[y]-'A'<=25))
l+=p[y]-'A'+1;
else if ((p[y]-'a'>=0)&&(p[y]-'a'<=25))
l+=p[y]-'a'+1;
while (l>10)
l=l/100+l/10%10+l%10;
for (int y=0;y<h.length();y++)

i+=h[y]-'A'+1;
else if ((h[y]-'a'>=0)&&(h[y]-'a'<=25))
i+=h[y]-'a'+1;
while (i>10)
i=i/100+i/10%10+i%10;
if ((i==0)&&(l==0)) cout<<endl;
else if (i>l)

}ow why it get W.A............[cpp][/cpp]

[pavelph]

Sorry, I didn't read you code. But today I get accepted for this problem after some WAs. My mistake was that program hadn't worked with words like

Code: Select all

@@
123

- sum of their "characters" is 0 and you must to find 0/0.
Realy in this case you should output clear line.

[abhijit]

cin.getline(b,25);
scanf("%s",b);

Have u submitted these two lines as-is ? Then, that might be the problem.

[Dani Rodrigo]

Hi,
I received many times WA because I use to read scanf ("%s",a) to get the names. This have a problem, when it finds a space, it stops reading.
Finally I got AC usint scanf ("%[^\n]");

[Niaz]

Use gets() to take inputs.

[MrED]

I did the same mistake as minskcity did.

His sum is wrong because 10 is a final sum for him.

Consider input
EE
E

His answer would be
50.00 %
But correct would be:
20.00 %
