Some Merge Sort Facts

By Tapos Pal
Below are some of the facts about Merge Sort

  • Uses the divide-and-conquer paradigm
  • Average and Worst case - O(nlogn)
  • Merge sort is more efficient than Quick Sort for some types of lists if the data to be sorted can only be efficiently accessed sequentially
  • Most common implementation does not have in-place sorting. Normally it requires 2n spaces
  • It is a stable sort

Scala Learning: Finding Square Root

By
I am renewing my learning in Scala and I have started the course Functional Programming Principles in Scala  in Coursera. Here is some code which is taken from that course object SqrtCalculator extends App{ def abs(x: Double): Double = if(x < 0) - x else x def sqrt (x: Double) : Double = { def sqrtIterator(guess: Double): Double = if (isGoodEnough(guess)) guess else sqrtIterator(improve(guess)) def isGoodEnough(guess: Double): Boolean = abs(guess * guess - x) / x < 0.0001 def improve(guess: Double): Double = (guess + x / guess) / 2 sqrtIterator(1.0) } println(sqrt(2)) println(sqrt(3)) println(sqrt(4)) println(sqrt(1e60)) } Output: 1.4142156862745097 1.7320508100147274 2.0000000929222947 1.0000000031080746E30 Process finished with exit code 0

Here is the process Open "Termial" Run command "sudo dscl . delete /Users/<hidden user's short name>" You are done

Problem Solving: Implement an algorithm to delete a node in the middle of a single linked list, given only access to that node

By Tapos Pal
Problem Implement an algorithm to delete a node in the middle of a single linked list, given only access to that node EXAMPLE Input: the node ‘c’ from the linked list a->b->c->d->e Result: nothing is returned, but the new linked list looks like a->b->d->e Solution The question is a bit confusing. I first though its asking to remove the middle element of the list and I thought we have the full list. But later I think I got it. As per my understanding is we clear the node which we have access only and it will be somewhere in the middle. What we can do, we can migrate the data from next one to this one and set next to next of next. Code https://github.com/tapos/ctci/tree/master/src/p23
