Since solution assumes single digit numbers it should state the same in the problem statement.

Hi @Peter_Litvak, the example given was in single digits but this solution is applicable for any digits like single, double, and so on.
I don’t think the way solution is presented will work for more than single digit number.
Looking at the:
char chr = input.charAt(i);
if (!Character.isDigit(chr))
part
Hey @Peter_Litvak, but after breaking the digits we are checking the input whether it is an operator or a digit. We are breaking the equation into two parts and making recursive calls. You can try with double digits input.
