Count number of occurrences in a sorted array using binary search We can also use a binary search. Using binary search we need o find two things, one is the first occurrence of the element and another is the last occurrence of the element. ...

Let there is a function f(i) this takes single argument i in range 0 to n-2, and does the operation: if A[i] > A[i+1], swap the values of A[i] and A[i+1]. We have to count number of iterations to make array A sorted, for the first time. So, if the input is like...

Binary Search will be used to find such position. Then insert the element at that position and the position itself will tell the elements smaller than the current element in the vector as it is already sorted. Store this value in a result array for every such element. Print the result arra...

1. Merge sort array A and create a copy (array B) 2. Take A[1] and find its position in sorted array B via a binary search. The number of inversions for this element will be one less than the index number of its position in B since every lower number that appears after the first...
