Examples: a) If array is {5, 2, 3, 1, 4}, then the function should return true because the array has consecutive numbers from 1 to 5. We have an array of integers and a given number so we have to find all pair in the array whose sum is equal to a given number. if n%2==1, n is an odd number – if the number is odd, the remainder is one. This is because the size of the array can be initialized dynamically a) If array is {5, 2, 3, 1, 4}, then the function should return true because the array has consecutive numbers from 1 to 5. b) If array is {83, 78, 80, 81, 79, 82}, then the function should return true because the array has consecutive … Save my name, email, and website in this browser for the next time I comment. mark the element visited. The time complexity of above solution is O(n) and auxiliary space used by the program is O(n). /* This method checks if array elements are consecutive */. Next, it will find the sum of odd numbers within this array using For Loop. The idea is to use hashing. A triplet is a value if it appears 3 consecutive times in the array. Example arr[] = {2, 24, 30, 26, 99, 25} 3. Input: { -1, 5, 4, 2, 0, 3, 1 } Output: Array contains consecutive integers from -1 to 5 Input: { 4, 2, 4, 3, 1 } Output: Array do not contain consecutive integers as element 4 is repeated Approach 1: In order for an array to contain consecutive integers, The difference between maximum and minimum element in it should be exactly n-1. If the whole array is consecutive then return null 2. class FirstNonConsecutive { static Integer find(final int[] array) { for (int i=0; i Algorithm > Check if Array Elements are Consecutive. In the book, the code has a bug that is made on purpose and they challenge you to fix it. The assignment can be found here. Find the Inorder successor of the given node […], Your email address will not be published. In the book, the code has a bug that is made on purpose and they challenge you to fix it. One Solution is to first sort the array and find the longest subarray with consecutive elements.Time complexity of this solution is O(nLogn). if ( Sum = = N):   i think my solution doesnot work for cases like (1,4,2,2} . 6) find the sum and product of all the elements in the array and store as sum1 and product1, max – min == n-1, first condition can also be written as sum == ((min + max) * n) /2. One of the tasks was to keep deleting 3 consecutive same integers from the array until the list is either empty or has no 3 consecutive same numbers. Suppose you have an integer array.This array should be treated as a circular array.The last value of an array will be connected to the first array, a n ⇒ a1. The above works with a little modification: Input:  { -1, 5, 4, 2, 0, 3, 1 } while (start < end): # Check if there exist any sequence. We can solve this problem in O(n) time using an Efficient Solution.The idea is … Check if it is possible to have […], If you want to practice data structure and algorithm programs, you can go through 100+ data structure and algorithm programs.
