Started with Merge sort and its time complexity, did merging using making new objects of the array and also did learnt about inplace merge sorting within the same array without creating the object of the array for merge sorting. Also learnt about dynamic routing a bit more and how to add navlinks in react and what is the main difference between navlinks and links in react: navlinks are basically used for navbars or highlighting the link whereas links are for normal adding the links, also we can add css in the navlinks using the a.active attribute in css or also using js in the same route file. That was all, then did attend my college and learnt about double integration and about elasticity in principle of microeconomics.
