You mind posting your solution? Don’t forget to format your code if you’re posting your code. You may post an ideone link.
/* package codechef; // don't place package name! */
import java.util.;
import java.lang.;
import java.io.*;
/* Name of the class has to be “Main” only if the class is public. */
class Codechef
{
public static void main (String[] args) throws java.lang.Exception
{
// your code goes here
// Scanner sc=new Scanner (System.in);
// int t =sc.nextInt();
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
int t =Integer.parseInt(br.readLine().trim());
while(t–>0)
{
String s[]=br.readLine().trim().split(“\s+”);
int n=Integer.parseInt(s[0]);
int m=Integer.parseInt(s[1]);
int p[]=new int[n];
int q[]=new int[m];
int a[]=new int[n+m-1];
s=br.readLine().trim().split(“\s+”);
for(int i=0;i<n;i++)
{
p[i]=Integer.parseInt(s[i]);
}
s=br.readLine().trim().split(“\s+”);
for(int i=0;i<m;i++)
{
q[i]=Integer.parseInt(s[i]);
}
for(int i=0;i<n;i++)
{
for(int j=0;j<m;j++)
{
a[i+j] +=p[i]*q[j];
}
}
for(int i=0;i<a.length;i++)
System.out.print(a[i]+" ");
System.out.println();
}
}
}
oops you forgot to format the whole code!
If you are having trouble formatting the code, please save your code to a pastebin and share the link here!

- you need more than 4 bytes
of storage for numbers that can be as large as 1410065408000
thanks
if you are programming in c++ , then ,
use long long int instead of int .
use fast way of extracting input and showing output .
use this :-
typedef long long int ll;
ios_base::sync_with_stdio(false);
cout.tie(NULL);
cin.tie(NULL);
My code also works fine in local IDE but getting WA when submitting.
import java.util.*;
class Expression{
public static void main(String[] ar) {
Scanner sc = new Scanner(System.in);
int t = sc.nextInt();
if(t > 10)
return;
while(t --> 0){
int np = sc.nextInt();
int nq = sc.nextInt();
long[] p = new long[np];
long[] q = new long[nq];
for(int i =0; i < np; i++){
p[i] = sc.nextInt();
}
for(int i =0; i < nq; i++){
q[i] = sc.nextInt();
}
long[] a = new long[np+nq-1];
for(int i = 0; i < np; i++){
for(int j = 0; j < nq; j++){
a[i+j] = a[i+j] + (p[i] * q[j]);
}
}
String ans = "";
for(int i =0; i < a.length; i++)
ans += a[i]+" ";
System.out.println(ans.trim());
}
}
}
