Amazing, i am not a hindi native speaker but i understood your explanation perfectly. Nice idea of doing a run through the array and explaining k and y-k and maintaining count of prefix sum occurance.

[@layashmaveeramalla2251]

[@ridgeadam8442]

I know Im randomly asking but does any of you know of a trick to get back into an Instagram account? I stupidly lost my login password. I would appreciate any assistance you can offer me

[@isaacbobby8571]

@Ridge Adam Instablaster ;)

[@ridgeadam8442]

[@akhileshkumarsingh3322]

gajab!!

[@eshanikabhattacharjee383]

how to get the intuition for such tricks

[@hiteshbhatia5609]

but how to print all those subarrays because if frequency of any sum is greater then 1 then how would we get more then 1 subarrays starting index from hashmap so that we can print all subarrays?

[@rajugoud6465]

[@mohitv7405]

How can we display the subarray?

[@adarshupadhyay8738]

sum 15 has a frequency 2 but bhaiya in the second occurence of sum 15 you have written 1 below it. it should be 2 not 1.

[@sauravsemwal1346]

Sir , aapka explanation bhut bdiya hai... Video ke title me leetcode problem no. bhi dal do easily search me aayega.....

[@Pepcoding]

Ji.

[@AI_focus]

Python implementation: def subarraySum( nums: List[int], k: int) -> int: map_freq={} sum_count=0 ans=0 map_freq[0]=1 for i in range(len(nums)): sum_count+=nums[i] if (sum_count-k) in map_freq: ans+=map_freq.get(sum_count-k) if sum_count in map_freq: map_freq[sum_count]=map_freq[sum_count]+1 else: map_freq[sum_count]=1 return ans

[@hannanhub1717]

[@sahilgupta7001]

what if we want each subarray also, then how will we solve it

[@sahilgupta7001]

@@Kashish_Batra thank you, i thought about this solution but wasn't sure if it is the best we can get, so just wanted to ask if you know about any further optimization

[@aryashjain7893]

what if we take target-sum instead

[@1991deeps]

You should write continuous sub-array as this solution would not do for non-continuous sub-arrays.

[@WizardsOfCode7]

but this is not working for array {1,2,3,4} and target value :6 output should be 2 ->{1,2,3} and {2,4} , but it is showing 1

[@coolgamerplayer2964]

it is talking about subarray not subesquence

[@sashantpardeshi2210]

Time complexity - O(n.m) n - length of array. m - lenth of hash map for search operations.

[@akshhay]

Search in hashmap is O(1)

[@sashantpardeshi2210]

@@akshhay when there is hash collision then ??
