What is a self aware number?
A self-descriptive number is an integer n in given base b is b digits long in which each digit at position p (the most significant digit being at position 0 and the least significant at position b – 1) counts how many times a digit p is in n. For example in base 10, 6210001000 is a self descriptive number.
What is number value?
The value refers to the worth of each digit depending on where it lies in the number. We calculate it by multiplying the place value and face value of the digit. Value=Place Value × Face Value. For instance: If we consider a number 45. Here the digit 4 is in the tens column.
