The smallest missing integer
WebGiven an array that includes positive and negative numbers, write a program to find the smallest missing positive integer. Example 1 Input: X[] = [2, -9, 5, 11, 1, -10, 7], Output: 3 Explanation: Consecutive positive integers 1 and 2 are present in the array. So the first missing positive is 3. Example 2 Input: X[] = [2, 3, -2, 1], Output: 4 WebDec 4, 2024 · K-th missing element in an unsorted array. Smallest prime number missing in an array.

Did you know?
WebThe problem comes from Codility programming training and it sounds as follows: we have an array (A []) with n (ranging from 1 to 100,000) elements and these are our parameters. The elements of the array are integers from −2,147,483,648 to 2,147,483,647, and we need to find smallest positive integer that is NOT in the array. WebFeb 13, 2024 · The smallest positive missing number in the array is: 3. We are passing the input unsorted array to the findNum () function. In findNum (), we will run two for loops. The outer for loop will run from 1 to size (array)+1. For each value of outer for loop, we will first set the flag to False.
WebJan 13, 2024 · Another Method: The idea is to use Recursive Binary Search to find the smallest missing number. Below is the illustration with the help of steps: If the first element of the array is not 0, then the smallest missing number is 0. If the last elements of the array is N-1, then the smallest missing number is N. WebDec 29, 2024 · A Computer Science portal for geeks.
