Which number in the sequence has the highest sum of its digits?
Input: n = 100 Output: 99 99 is the largest number in range from 1 to 100 with maximum sum of digits.
What is square submatrix?
matrices. We have 2n×2n binary matrix with k of its elements are 1. We are searching for an n×n submatrix full of 1s.
What is largest value number?
The number 2,147,483,647 (or hexadecimal 7FFFFFFF16) is the maximum positive value for a 32-bit signed binary integer in computing. It is therefore the maximum value for variables declared as integers (e.g., as int ) in many programming languages.
Is 6 a Niven number?
A number which is a harshad number in every number base is called an all-harshad number, or an all-Niven number. There are only four all-harshad numbers: 1, 2, 4, and 6 (The number 12 is a harshad number in all bases except octal).
Which is the sum of digits of a square number?
Now the sum of digits of any perfect square also follow the rule. And hence your answer must be the number of numbers from 1 to 2007 of the forms 9 m, or 9 m + 1 , or 9 m + 4 or 9 m + 7. By far the answer given by Manthanein as “Method 2” seems to me the most enlightening.
How to find the smallest number with sum of digits?
Given sum of digits and sum of square of digits . Find the smallest number with given sum of digits and sum of the square of digits. The number should not contain more than 100 digits. Print -1 if no such number exists or if the number of digits is more than 100.
How to find the largest number with given number of digits?
The idea is to one by one fill all digits from leftmost to rightmost (or from most significant digit to least significant). We compare the remaining sum with 9 if the remaining sum is more than 9, we put 9 at the current position, else we put the remaining sum.
Which is the smallest 2 digit number in the world?
Given an integer N, find the smallest N digit number such that the sum of the square of digits (in decimal representation) of the number is also a perfect square. If no such number exists, print -1. The smallest possible 2 digit number whose sum of square of digits is a perfect square is 34 because 3 2 + 4 2 = 5 2.
