How do you find the missing and repeating numbers in an array?

How do you find the missing and repeating numbers in an array?

Approach:

1. Create a temp array temp[] of size n with all initial values as 0.
2. Traverse the input array arr[], and do following for each arr[i] if(temp[arr[i]] == 0) temp[arr[i]] = 1;
3. Traverse temp[] and output the array element having value as 0 (This is the missing element)

How do I find the closest element to an array?

So if the array is like [2, 5, 6, 7, 8, 8, 9] and the target number is 4, then closest element is 5. We can solve this by traversing through the given array and keep track of absolute difference of current element with every element. Finally return the element that has minimum absolute difference.

How to find missing element in sorted array?

An efficient solution is based on the divide and conquer algorithm that we have seen in binary search, the concept behind this solution is that the elements appearing before the missing element will have ar [i] – i = 1 and those appearing after the missing element will have ar [i] – i = 2. Attention reader! Don’t stop learning now.

How to find the missing number in a list?

The number m + 1 is located at a cell with index m, The number m + 2 is located at a cell with index m + 1, and so on. We can see that, the missing number m is the first cell whose value is not identical to its value. Therefore, it is required to search in an array to find the first cell whose value is not identical to its value.
