This time's challenge is a short one but it may take some time to think through.
Suppose, you have a number in cell A1. The challenge is to add 1 in all digits and come with a result.
Hence,
If A1=28, result would be 39.
If A1 = 123, result would be 123+111 = 234
If A1= 912, result would be 912+111 = 1023
If A1=1999, result would be 1999+1111 = 3110
If A1=9999, result would be 9999+1111 = 11110

Formula in cell B1:
=A1+REPT(1,LEN(A1))
