If it is a square matrix order n
Primary diagonal
if(i==j)
{
sum+=a[i][j];
}
Secondary diagonal
if(i==(n-1)-j)
{
sum+=a[i][j];
}

Can also be done using constructor overloading concept (by sending in different number of parameters)

use the following method:

mark the missing number as M and the duplicated as D

1) compute the sum of regular list of numbers from 1 to N call it RegularSum

2) compute the sum of your array (the one with M and D) call it MySum

now you know that MySum-M+D=RegularSum

this is one equation.

the second one uses multiplication:

3) compute the multiplication of numbers of regular list of numbers from 1 to N call it RegularMultiplication

4) compute the multiplication of numbers of your list  (the one with M and D) call it MyMultiplication

now you know that MyMultiplication=RegularMultiplication*D/M

at this point you have two equations with two parameters, solve and rule!

@vandita Just a minor correction i think we should go till n-1 only so the in for loop it should be and should use i+1 since nbrs are starting from 1 and not 0

Code
span style="font-style: italic;">//since 1 is stored at 0th position

You are given a matrix. The matrix elements are such that they are sorted both horizontally and vertically. Given an element of the matrix, your job is to obtain its position in an efficient manner.Example: 10 20 30 15 35 98 48 76 110Input: 76Output: 3rd row, 2nd column.
