This whole task will be completed in O(K) time where K is the total number of digits of N. Below is the implementation of the above approach: Time Complexity: O(n1*logn1 + n2*logn2), where n1 and n2 represents the lengths of the given strings.Auxiliary Space: O(1), no extra space is required, so it is a constant. Auxiliary Space: O(1) Find the Largest number with the given number of digits and sum of digits Greedy approach . ), where K is any digit from N.. Now to create the number Get Locale went all the way down to the thousandths place. Proof Binary single precision numbers lying in the half open interval [10 3 , 2 10 ) = [1000, 1024) have 10 bits to the left of the binary point, and 14 bits to the right of the binary point.
