can u please find problem in this one? It is just passing sample case
a,b=input().split()
c=input()
d=input()
if len(c)==2*int(a)-1 and len(d)==2*int(b)-1:
e=set(c)
f=set(d)
g=(e|f)
h=list(g)
h.sort()
h.remove(" ")
string=""
for element in h:
string=string+element
string=string+" "
i=list(string)
i.pop()
str1=""
for elements in i:
str1=str1+elements
print(str1)
why doesn’t this work?

This is showing WA for sample test 4. why?
My code shows correct solution of test 1 when I run it on my compiler. But, It gives wrong answer on test 1 when I submit it. Can anyone tell me the reason?
#include <bits/stdc++.h>
using namespace std;
int main(){
int n, m, len;
cin>>n>>m;
int A[n], B[m];
for (int p = 0; p < n; p++){
cin>>A[p];
}
for (int q = 0; q < m; q++){
cin>>B[q];
}
int i = 0, j = 0;
while (i < n && j < m){
if (A[i] < B[j]){
cout<<A[i]<<" ";
i++;
}
else if (B[j] < A[i]){
cout<<B[j]<<" ";
j++;
}
else{
cout<<A[i]<<" ";
i++, j++;
}
}
/* Print remaining elements of the larger array */
while(i < n){
cout<<A[i]<<" ";
i++;
}
while(j < m){
cout<<B[j]<<" ";
j++;
}
return 0;
}
Could someone please tell me what’s wrong with this code?
N,M=map(int,input().split())
H=list(map(str,input().split()))
G=list(map(str,input().split()))
L=[]
for i in range(N):
L.append(H[i])
for i in range(M):
if G[i] not in L:
L.append(G[i])
U=sorted(L)
K=" ".join(U)
print(K)
Extra space at the end caused WA 
a, b = map(int, input().strip().split())
c, d = input().strip().split(), input().strip().split()
c += d # join
c = list(dict.fromkeys(c)) # make unique
c.sort()
print(’ '.join(c))
I can’t understand why getting wrong answer?
Note: (c) is c in first bracket.
a = input()
c = input()
d = c.split()
d = set(d)
e = input()
f = e.split()
f = set(f)
g = d.union(f)
h = list(g)
h.sort()
j = ' '.join(map(str,h))
print(j)
What’s the problem?
WA in case 4, why?
@user.660051 You are sorting strings in lexicographical order (h in h.sort() is a list of strings). You are not sorting integers.
[REDACTED]
It was accepted!
but if I validate the input, that was wrong in second test
x, y = map(int, input().split())
isValid=1
if 0<x<100 and 0<y<100:
a = {int(num) for num in input().split(" ", x)}
b = {int(num) for num in input().split(" ", y)}
a=list(a)
b=list(b)
for i in range(len(a)):
if i==0: continue
elif a[i-1]>a[i]:
isValid=0
break
for i in range(len(b)):
if i==0: continue
elif b[i-1]>b[i]:
isValid=0
break
a=set(a)
b=set(b)
result= a.union(b)
if isValid:
print(' '.join(str(s) for s in result))
@Ataullah Your test isn’t accurate.
Set is an unordered and unindexed collection of items in Python.
In your code here:
a = {int(num) for num in input().split(" ", x)}
b = {int(num) for num in input().split(" ", y)}
You are reading the integers into two sets. You are losing the original order of the elements.
thanks for your help, I solved it
def make_elements_int(given_li: list):
all_int_li = []
for element in given_li:
if element != " ":
all_int_li.append(int(element))
else:
pass
return all_int_li
def main():
_ = str(input())
SET_A = set(input())
SET_B = set(input())
result = sorted(make_elements_int(list(SET_A | SET_B)))
print(*result, sep=" ")
if __name__ == "__main__":
main()
It shows WA on test case 2 but I can’t find the problem can anyone help me?
The issue lies in the fact that you are creating a set from the input string, resulting in a set of individual characters instead of a set of numbers. As a consequence, the output is not as expected. For instance, given the test case:
3 3
19 13 14
1 2 3
Your code produces the output
1 2 3 4 9
whereas it should output
1 2 3 13 14 19.
To fix this problem, you can modify the code by using input().split(' ') instead of input() to split the input string into a list of strings based on the space character. This will result in a list of numbers that can be used to create a set of distinct values.
For more information on how to take multiple inputs from the user in Python, you can refer to the following resources:
Good luck with your coding endeavors!
Thanks, for the information. While I did solve the problem later on, the answer might help others, who are also having similar problems 
What’s the problem in my code?
input_string1 = input()
array_elements1= input_string1.split()
array1 = [int(element) for element in array_elements1]
input_string2 = input()
array_elements2= input_string2.split()
array2 = [int(element) for element in array_elements2]
newArray = []
for element in array1:
if element not in newArray:
newArray.append(element)
for element in array2:
if element not in newArray:
newArray.append(element)
resultArray = sorted(newArray)
result = ' '.join(map(str, resultArray))
print(result)
You are missing to take input() of N and M.
Just add an input statement at the beginning of your code and it’ll work fine. Even though you don’t need the lengths of the arrays, you need to take the input.
Cuz now your code is considering N, M as the first array.
