Wrong Answer. !!!Wrong Answer Possibly your code doesn't work correctly for multiple test-cases (TCs). The first test case where your code failed: Input: 84 86 77 15 93 35 86 92 49 21 62 27 90 59 63 26 40 26 72 36 11 68 67 29 82 30 62 23 67 35 29 2 22 58 69 67 93 56 11 42 29 73 21 19 84 37 98 24 15 70 13 26 91 80 56 73 62 70 96 81 5 25 84 27 36 5 46 29 13 57 24 95 82 45 14 67 34 64 43 50 87 8 76 78 88 Its Correct output is: 4278 And Your Code's output is: 2412

I'm facing problem sir. If you will guide, then I can give a try.

You must it solve yourself

Looks easy

#include <stdio.h> int main() { //code int T,i,k=1,n,sum; scanf("%d",&T); int arr[n]; for(k=0;k<T;k++) { sum=0; scanf("%d",&n); for(i=0;i<n;i++) { scanf("%d",&arr[i]); sum = sum+arr[i]; } printf("%d\n",sum); } return 0; }

> int arr[n]; What is it?

> int arr[n]; What is it?

array

Artöm

Of which size?

Anonymous

with size

Artöm

n is not a constant exoression and is uninitialized

Artöm

Btw you dont even need array in this case

Anonymous

Btw you dont even need array in this case

in the question itself, it's mentioned to take array as an input

Artöm

Which doesnt mean you actually need to create it

Artöm

Array here is number sequence, not array in prigramming terms

And this is another one: #pragma omp parallel for private(m,j) for(i=0;i<N;i++) { for(j=0;j<N;j++){ C[i][j]=0.; // set initial value of resulting matrix C = 0 for(m=0;m<N;m++){ C[i][j]=A[i][m]*B[m][j]+C[i][j]; } // printf("C: %f \t",C[i][j]); } }

Anyone?

Is there a better way of doing this?, Blocks are made using a for (int x = 0; x < WORLD_WIDTH; x++) for (int y = 0; y < WORLD_HEIGHT; y++) for (int z = 0; z < WORLD_DEPTH; z++) {

The current blockAt code realy slows down my game by a lot, I wonder if any math can be done with the XYZ to get the index of it in the blocks vector.

You can order the vector, so that you can find the right block with simple arithmetic

How would i do that?

Javi

How would i do that?

The positions are just the coordinates in a 3d matrix. Order the positions and you won't have to search

hey guys, I have a question, Say I have a function which takes file as an argument, (file can be **argv contents or stdin), my main problem is that I don't know how to pass stdin as argument to that function

you want to pass value (file name) entered from command line into some function?

数学の恋人

you want to pass value (file name) entered from command line into some function?

yes

01000001011011010100000101101110

yes

pass the value from main() it must work

数学の恋人

pass the value from main() it must work

that's what I'm doing

01000001011011010100000101101110

that's what I'm doing

what is the error?

数学の恋人

I pass the file name like if (argc < 2) { someFunc(stdin); } else { for (int i = 1; i < argc; i++) { someFunc(argv[i]); } }

数学の恋人

I pass the file name like if (argc < 2) { someFunc(stdin); } else { for (int i = 1; i < argc; i++) { someFunc(argv[i]); } }

now my question is how should I pass stdin to the function which is inside the if

01000001011011010100000101101110

why dont you ask for values in if itself before calling the function?

01000001011011010100000101101110

if (argc < 2) { int bla; std::cin>>bla someFunc(bla); } else { for (int i = 1; i < argc; i++) { someFunc(argv[i]); } }

what do you mean?

Anonymous

the code is wrong

Anonymous

it lacks ) to the end of someFunc

数学の恋人

oh sorry

数学の恋人

I pass the file name like if (argc < 2) { someFunc(stdin); } else { for (int i = 1; i < argc; i++) { someFunc(argv[i]); } }

files := os.Args[1:] var source string if len(files) == 0 { someFunc(os.Stdin) source = "Stdin" } else { for _, arg := range files { source = arg v, err := os.Open(arg) if err != nil { fmt.Fprintf(os.Stderr, "someProgram: %v\n", err) continue } someFunc(v) v.Close() } }

this is how I would do in Go
