Explanation of Solution

O(n) time algorithm to find the missing number:

To find the missing number in linear space let us follow the steps as follows:

Algorithm:

Step 1: Initially, get the sum of numbers "0" to "n-1".

Step 2: Next, determine the sum of all values in "A".

        total = n(n+1) / 2;

Step 3: Next, subtract sum values from sum of all array "A"...

Given an integer array Arr of size N the task is to find the count of elements whose value is greater than all of its prior elements. Note : 1st element of the array should be considered in the count of the result. For example, Arr={7,4,8,2,9} As 7 is the first element, it will consider in the result. 8 and 9 are also the elements that are greater than all of its previous elements. Since total of 3 elements is present in the array that meets the condition. Hence the output = 3.
Create a array of size n and poulate it with random numbers in range @ to 150. Print the maximum number in the array. Take n as input by user. Write whole code in main function only.Given n>=1 and n
“A” array has a members and “B” array has b members which are sorted. I need an algorithm to find the k-th member in a new array which is a mix of “A” and “B”. The runtime must be O(log(a+b))
