Sum of two arrays

#1

Can you provide hint for this?

#2

hello @shubhangis248

just do simple addition , that we use to do in our daily life.
i.e first add last digits of given numbers and forward its carray to left , again perform addition on next digits and forward their carray to next . repeat this for all digits thats it.

Algorithm:

1.Traverse both the arrays simultaneously from the end until we reach the 0th index of either of the array.
2.While traversing each element of array, add an element from both arrays and carry from the previous sum.
…………2.1 Store the unit digit of the sum(obtained by doing - sum%10) in the ans array.
…………2.2 forward carry(obtained by doing - sum/10) for the next index sum.
3.After the loop ends we are left with one of the arrays and the carry.
4.We will now repeat step 2 but now for one array which is left after the loop.
5.If carry !=0 then store the carry in the 0th index of ans array.
6.Print the ans array .

whta is wrong in this?

#4

add space after comma and then try

#5

compliation successful but not passing test cases

#6

@shubhangis248
a) u r not reading n and m.

b) k will become zero after the while loop . so to print array again u need to reset its value

c) u r printing from 0 th index , what if there is no carry generated (in such case u need to begin from 1)

what is wrong in this code?
