I don't understand your question. Can you please describe in detail?

I think this is very intuitive . We have to go through all the elements and then increment each element by 1 until we either reach an element which is less than or equal to eight or the first element if we reach the first element we have to shift the whole array right and add 1 in starting.

int[] incerement(int a[]){
		for(int i = a.length-1;i>0;i--){
			if(a[i]<=8)
			{
				a[i]++;
				break;
			}
			else
			{
				a[i]=0
			}
		}
		if(i==0&&a[i]==0)
		{
			b=new int[a.length+1];
			b[0]=1;
			return b;
		}
		return a;
	
	}

Python solution:

def incrementNum(nums):
    numStr = ""
    for num in nums:
        numStr.append(str(num))
    return list(str(int(numStr) + 1 ))
