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

sum+=a[i][j];
}

Using HashSet as in case of jave will be better than HashMap. We can just iterate over the characters of both the strings and put them in set.

You have an array of size '2n' of these, 'n+1' elements are distinct and 1 element is repeated 'n' times. You must find the repeated element and say how many times it has repeated. Your solution must use minimum no. of comparisons. Also, say how many comparisons your solution will make in the worst case?

Since an element is repeated more than half the occurance of the array, for every two didtinct elements discard them from the array. At the end of the loop, the most repeated element will be left.

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.

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
