Are there Missing numbers in a text file?
Let’s suppose you have a text file of consecutive numbers, such as below, with each number on its own line: However, there are some missing numbers and gaps. In the example above, 5 is missing, and there are two gaps: between 8 and 11 and also between 14 and 17.
Are there Missing numbers between 8 and 11?
In the example above, 5 is missing, and there are two gaps: between 8 and 11 and also between 14 and 17. Of course, in this example it is easy to see the problems just by looking at it, but if we were talking about thousands of numbers, it would be too cumbersome to locate the gaps by eye.
How do you find the missing numerator of a fraction?

How to find the missing number in an array?
Approach: The length of the array is n-1. So the sum of all n elements, i.e sum of numbers from 1 to n can be calculated using the formula n* (n+1)/2. Now find the sum of all the elements in the array and subtract it from the sum of first n natural numbers, it will be the value of the missing element.
How to find the missing y and X?
Method 4 (Make two equations) Approach: 1 Let x be the missing and y be the repeating element. 2 Get the sum of all numbers using formula S = n (n+1)/2 – x + y 3 Get product of all numbers using formula P = 1*2*3*…*n * y / x 4 The above two steps give us two equations, we can solve the equations and get the values of x and y.
