Same man, i was struggling to get up from bed the entire day. But finally at 11pm i decided i will atlest spend the last hout of my day working towards my financial independece

[@ravenin9612]

I first watched this video and i understood this partially, its fascinating how a few lines of code can be so confusing. Maybe thats why dsa is still considered to be very hard. I finally understood this concept after writing the code in paper and analyzing each iteration and what happens after the same. If anyone dont understand the topic, just do the same and you will understand it.

khub sundar, osadharon🙂

[@28_g_pawanvinayakawasthi23]

Hi Striver @takeUforward , in the insertion sort ,the outer loop i.e. the loop with i should start with i=1 instead of i=0 because the j takes the value of i and in the while loop it says j should be greater than 0 so it will always stand false for the first iteration ( j=i=0) and moreover we don't need to check the correct order of single element . Please correct me if i am wrong because i am just saying what I understood .

[@ShubhraneelChakraborty-cj8zm]

Yeah you are right I believe. When I saw the outer loop, I was thinking the same thing and when I run the code, it prints the same output as with i=0, just as I thought it would be during the dry run.

[@Raj10185]

one suggession for insertion sort why we run outerloop from i = 0 we should start directly from i = 1 till iarr[j]) { int temp = arr[j]; arr[j]=arr[j-1]; arr[j-1]=temp; j--; }

[@AryanRishi-vk6et]

it wouldn't impact anything if the outer loop is running from 0 to n-1 then when i = j = 0 it will no go into the while loop and move on to next iteration of i

[@dhruvverma1001]

I want to understand how does is not give index out of bound error by accessing -1, or it does short curcuit

[@coder-2026]

@@dhruvverma1001 j>0, it will start forom j=1. for j=1 , the comparison will be between arr[0] and arr[1]

[@yashvardhansingh5341]

For bubble sort striver you are using i>=1 in outer loop in the pseudo code but while using the code editor you are using i>=0.

[@ankitpal8044]

Same doubt??

[@nirbhaybhardwaj4330]

there is no need of going till i>=0 . but if you go , this is also right .....i=0 is automatically got minimum number when we are sorting

[@swarupsaha9064]

Hi Striver, At the Section of Selection Sort. I believe there might be a bit misunderstanding on calculating the Time complexity part: If we are given n elements, then in the first pass, it will do n-1 comparisons; in the second pass, it will do n-2; in the third pass, it will do n-3 and so on. Thus, the total number of comparisons can be found by; - (n-1) + (n-2) + (n-3) + ..... + 1 So i believe it should be : n(n -1)/ 2 At the end the TC is O(n^2), but i thought this should be the approach.

[@sdfsdf-f1j]

man you really dont know any maths , just open the bracket n2-n by 2 remove the constans and less imp terms and it boils down to n2 . ....
