1920. Build Array from Permutation | Zero to FAANG Kunal | Assignment Solution | Leetcode | Shapnesh

[@karunyadav6345]

Amazing solution bro.🔥.. Kindly please solve my one doubt.. why can't we use single for loop and write both the conditions in that for loop only ..l have dry runned the code but l'm not able to understand why the answer is coming different when l am using both the conditions in one for loop only ....please please help me 🙏

[@karunyadav6345]

Kindly please reply brother Apka hi Sahara h ab🙏 ap ignore mat karna plz

[@ProgrammersZone]

@@karunyadav6345 Yepp It will not give the same result if we run both the conditions in one loop as the value of each index changes in each iteration for example if our original array is [1, 2, 3, 0] and then after first iteration it becomes [2, 2, 3, 0] now after second iteration it becomes [2, 3, 3 0] after third iteration it becomes [2,3, 0, 0] and the answer till here is correct but once you do it for last iteration you'll get nums[nums[3]] as 2 which you should have got as 1 if you had gone in the videos approch so as long as the numbers are in increasing order it is fine but the testcases fail when numbers are in non increasing order so you must write both of them differently I hope this helps :)

tum bahut sahi kam kar rahe ho mansukh bhai

[@kallabhargavi-d7j]

nums=[0,2,1,5,3,4] result1=[] for i in range(len(nums)): result=nums[nums[i]] result1.append(result) print(result1)

[@Kumkum-n9v]

how did you come up with this approach? I mean the thought process

[@prekshathakkar5846]

Very good explanation. But I have one doubt while doing the second method, how can we derive the equation: nums[i] = nums[i] + n*(nums[nums[i]] % n) I mean how do we come to know that we need to use this equation?

[@amitprajapati3630]

Nice solution brother

[@SHUBHAMSINGH-f2g]

nice explain sir😊

[@deepakchaudhary01]

I really loved the way you explained, much appreciated !!

thanks bruhh keep it up tumhe maang hi milega aise meri manokhmna

Meri bhi aapke liye _/\_ Keep going :)

[@shubhammaske3504]

Nice ... But how to find such type of logic or formula during attending question. could you please explain

[@ProgrammersZone]

Just write 4-5 examples and you'll observe the pattern even if you aren't able to its fine eventually with time it will happen but make sure ki har questions ko solve karne ke baad solution section me naye naye ways dekho with time tumhare mann me bhi click hone lagenge ye ideas

Bhai maja aa gya solution ma

[@ronitbanerjee2678]

Great explanation... thanks alot

Dhanyawad bhai..hmse 1 Q v nhi bnta hai aap kaisa soch lete ho..? kunal bhaiya ka videos dekhna suru kiye the phle Q me hi fass gye 😑

[@ProgrammersZone]

Bhai kunal ke videos to theek hai but follow Take U Forward and their videos for DSA. Follow A2Z DSA sheet and try the questions by yourself and look leetcode discuss section

[@gauravmishra7158]

so this means aise questions jisne lgae ho whi kr skta hai qki ye formula pta hona chahie already right?

Just solve more and more examples you'll notice the pattern, also try to learn different approaches for one question.

bhai kunal bhai ke hi assignments bahut hai ya phir aur bhi karne chahiye khudh se agar khudh se karne hai to bata do kaha se karu please bhaiya

[@ProgrammersZone]

Depends upon you, if you are into 1-2 year focus on codechef and codeforces and if you want to prepare for interviews do leetcode :)

[@kunalpatil7473]

Can someone give me full solution programm for this code please. I am Not able to run this in intellij idea.

how do we derive this formula? idea kaise aayega ki yeh formula banna chahiye?
