Fifth, After failed in 3rd time see my solution. So the easiest approach would append the '0' in the given array and sort it and return the element next to '0' Editorial . Number formation is the binary number from the bits status in the array L to R. 1 X : Flip the Xth bit in the array. Just Smaller Number: Hackerearth Problem Statement: Given an array A A of length N N and a number K K, find the greatest number in the array A A that is smaller than K K. Input: First line contains two space separated integer N, (1 ≤ N ≤ 10 5) N, (1 ≤ N ≤ 10 5) and Q, (1 ≤ Q ≤ 10 5) Q, (1 ≤ Q ≤ 10 5), number of elements in the array A A, and number of queries. Complexity: time complexity is O(n*log(n)) // sorting. It just indicates that your code correctly compiled and ran successfully against the sample input. Posted on March 19, 2015 by Martin. Consider the string indexing to be 1-based. In cases where partial marking is allowed, you will awarded partial marks for the number of test cases your solution passes. You have been given a positive integer N N. You need to find and print the Factorial of this number. A short description of the problem for which a candidate should provide a solution or an answer. The string $$S$$ consists of digits from 1-9. SOLUTION FOR SEATING ARRANGEMENT PROBLEM - HACKEREARTH PROBLEM Akash and Vishal are quite fond of travelling. What would you like to do?

Few valid numbers are 147,159,348 etc.. but 124 and 396 are invalid. Among all the valid numbers that can be formed, your task is to determine the $$K^{th}$$number if all the unique valid numbers are sorted in ascending order. In this case, it will make it easier to determine which pair or pairs of elements have the smallest absolute difference between them. Monk hates to cross these bridges as they require a lot of effort. $$answer = (answer \times 2$$) % $$(10^9+7)$$ You have to find out the member who wins the game. You need to divide the string into blocks such that the $$i^{th}$$  block contains the elements from the index$$((i-1)*X + 1)$$ to $$min(N,(i*X))$$ (both inclusive). Embed.
