Problem: 821`763=
Explanation:
The first number is 821, FN=[8,2,1]. The second number is 763, SN=[7,6,3]. Since FN [8,2,1] has 3 digits, SN [7,6,3] has 3 digits, thus the maximum number of digits is 3. In each subsequent step, we remove one number from the beginning of FN and one from the beginning of SN.
Length of FN is 3. FN=[8,2,1]. Length of SN is 3. SN=[7,6,3]. FN[3]=8. SN[3]=7. C[3]=0.  Since 8*7=56, 56%10=6, 56//10=5. Length of A is 1. Thus A=[6]. Since 5 is odd, we change the value of C. Since C[3]=0, C[2]=1. 
Length of FN is 2. FN=[2,1]. Length of SN is 2. SN=[6,3]. FN[2]=2. SN[2]=6. C[2]=1. Since 2*6=12, 12%10=2, 12//10=1. Length of A is 2. Thus A=[6,2]. Since 1 is odd, we change the value of C. Since C[2]=1, C[1]=0.
Length of FN is 1. FN=[1]. Length of SN is 1. SN=[3]. FN[1]=1. SN[1]=3. C[1]=0. Since 1*3=4, 4%10=4, 4//10=0. Length of A is 3. Thus A=[6,2,4]. Since 0 is even, we do not change  the value of C. Since C[1]=0, C[0]=0.
There are no more digits and C[0]=0. Thus the process is complete. Sin
