Not able to understand the sample test case

#1

please explain how the sample output results from the sample input

#2

Hello @pragyachoudhary1111,

Consider the addition of arrays as the sum of two numbers that you have learnt in mathematics.
Let’s understand this with the help of the sample input given in the question:
4
1 0 2 9
5
3 4 5 6 7

for once, consider these array as two numbers: 1029 and 34567.
Now adding these two the way you do in maths:
1029+34567= 35596

Thus, the output is:
3, 5, 5, 9, 6, END (This is just the output format that can be easily created using count statements)

Hope, this would help.
Give a like, if you are satisfied.
