Wrong testcases in my solution

#1

import java.util.;
public class Main {
static int calSumUtil(int a[], int b[],int n, int m){
int[] sum= new int[n];
int i = n - 1, j = m - 1, k = n - 1;
int carry = 0, s = 0;
while (j >= 0){
s = a[i] + b[j] + carry;
sum[k] = (s % 10);
carry = s / 10;
k–;
i–;
j–;
}
while (i >= 0){
s = a[i] + carry;
sum[k] = (s % 10);
carry = s / 10;
i–;
k–;
}
int ans = 0;
if (carry == 1)
ans = 10;
for ( i = 0; i <= n - 1; i++) {
ans =ans+sum[i];
ans =ans10;
}
return ans / 10;
}
static int calSum(int a[], int b[], int n,int m){
if (n >= m)
return calSumUtil(a, b, n, m);
else
return calSumUtil(b, a, m, n);
}
public static void main(String[] args){
Scanner sc=new Scanner(System.in);
int n=sc.nextInt();
int []a=new int[n];
for(int i=0;i<a.length;i++) {
a[i]=sc.nextInt();
}
int m=sc.nextInt();
int []b=new int[m];
for(int i=0;i<b.length;i++) {
b[i]=sc.nextInt();
}
System.out.print(calSum(a, b, n, m));
System.out.print(“END”);
sc.close();
}
}
here i am getting correct output but my testcases are wrong,why?

Paste your code on the IDE. Click on save and share the corresponding URL with me

#5

sir can’t you copy and paste the code on your device?

#6

The code isn’t formatted correctly. Half of it is in italics and a few symbols have been ignored. Kindly share the code on online IDE

here is the code import java.util.*;
public class Sumarraycd {
static int calSumUtil(int a[], int b[],int n, int m){
int[] sum= new int[n];
int i = n - 1, j = m - 1, k = n - 1;
int carry = 0, s = 0;
while (j
s = a[i] + b[j] + carry;
sum[k] = (s % 10);
carry = s / 10;
k–;
i–;
j–;
}
while (i >= 0){
s = a[i] + carry;
sum[k] = (s % 10);
carry = s / 10;
i–;
k–;
}
int ans = 0;
if (carry == 1)
ans = 10;
for ( i = 0; i <= n - 1; i++) {
ans += sum[i];
ans *= 10;
}
return ans / 10;
}
static int calSum(int a[], int b[], int n,int m){
if (n >= m)
return calSumUtil(a, b, n, m);
else
return calSumUtil(b, a, m, n);
}
public static void main(String[] args){
Scanner sc=new Scanner(System.in);
int n=sc.nextInt();
int []a=new int[n];
for(int i=0;i<a.length;i++) {
a[i]=sc.nextInt();
}
int m=sc.nextInt();
int []b=new int[m];
for(int i=0;i<b.length;i++) {
b[i]=sc.nextInt();
}
System.out.println(calSum(a, b, n, m));
sc.close();
}
}

You have assumed that n is always greater than m which is incorrect.
Example: if the input arrays are
[1,2]
[4,5,6]

You need to consider the case where n is smaller than n.
Also, your output pattern doesn’t matches with the expected output.
For the input
4
1 0 2 9
5
3 4 5 6 7

You need to output the pattern in this format:
3, 5, 5, 9, 6, END
