386 - Perfect Cubes [WA]

I've compared the output using FC with some other's output and they match, can anybody tell what's going on? #include <cstdio> #include <cmath> #include <iostream> #include <cstdlib> using namespace std; bool cubes[80000001]={false}; struct lc { int num; int i, j, k; } list[500]={0,0,0,0}; int cmp(c...

Re: 11466 - Largest Prime Divisor

I've been gulping loads of WAs on this. I've read about negative numbers and have handled them in both the ways that I've seen on uvatookit.com and another blog. But still can't figure the problem out. I do a sieve till 10000000 then store all primes. Keep on dividing the given number the list ends ...

Re: Bsearch---built in

If you're talking about bsearching on an array of structs then you need to have your query in the same kind of struct. Then just customize the compare function for strcmp(), if that's what u r asking.

Re: Beat the spread -getting WA

You're printing the two numbers on separate lines. They should be on the same line. See the problem's output sample. I don't think there is any other fault.

Re: 424 - Integer Inquiry RE

The memory limits are enough why use so small limits on arrays. Use 1000.

Re: How to know what was the Wrong Answer

UVA OJ doesn't provide answers it is getting from your program. It's done partially in USACO but not even a bit in UVA. If you're stuck at some prob, just browse the forum for it. People usually provide a lot of help.

Re: 10197 - Learning Portuguese

You can't use the "nos" and "vos" as copy-paste strings in the array. For them you have to use 243 explicitly. Like this: for (i=0 ; i<6 ; i++) { if (i==3) { putchar('n'); putchar(243); putchar('s'); } else if (i==4) { putchar('v'); putchar(243); putchar('s'); } else printf("%s",t_rep[i]); for (j=1 ...

Re: 119 Why WA??

One of the craziest hard-to-get-AC experience To get AC you need three things. 1. Check Jan's Sample I/O in this thread and correct it. 2. Check these Sample I/0 and correct it. Input 2 Fat Dude Fat 1000 0 Dude 100 1 Fat Output Fat 100 Dude -100 3. Print a blank line after each case except the last ...
