90 + (1 * 8) + (2 * 3) - 7 + 4 + 5 - 6
-99
It could be: 1234567890 = 1
22, 28, 82 and 88.
874321 is the largest number made from all these digits.
The sum of all the digits of all the positive integers that are less than 100 is 4,950.
You would need infinitely many digits to write all numbers. However, to write all whole number (integers) you would need 4243.
There are 3,265,920 numbers that can be formed using all the digits. The answer to the question will depend on which one of these.
-100 all the way to -999
first read nd write all individual digits then goto sum funtion use by adding all individual digits..
