I do not know what to do with this help me please.

1. Consider the problem of adding two large positive integers, each at most twnty(20) digits long. One solution is to store the integers in an array where a single digit is placed in a single component of the array. for example the number 1,418,436,029 can be stored as shown below:

/ / / / / 1 / 4 / 1 / 8 / 4 / 3 / 6 / 0 / 2 / 9 /
0 1 2 ... 10 11 12 13 14 15 16 17 18 19

design an algorithm called addLong(int1,int2, sum) that will take two positive integers stored in two separtate arrays, in Array1 and Array2 in the manner described earlier, take their sum and store the result in a third called sumArray.

can someone help me with this?
