Amazing explanation 🔥🔥

[@AnkitSingh-xp7mm]

We can also replace all zero's with -3, then generate a prefix sum. After that, this problem is similar to - longest subarray with equal 0s & 1s.

[@raghavgarg8024]

what if n=4 arr=1,0,1,1 is this approch works now??

[@AnkitSingh-xp7mm]

@@raghavgarg8024 There are two cases based on prefix sum: 1.) When we get prefix[I] == 0 2.) When prefix[I] == prefix[j] In both cases, we can check the number of elements(Subarray) should be multiple of 3: 1.) number of subarray elements = i+1 2.) number of subarray elements = j-i

[@jatinbhatoya8420]

@@AnkitSingh-xp7mm i like your approach. i thought same like you

[@sakshamp4488]

is this question avilable on leetcode for submission?

[@jatinbhatoya8420]

If there is only 111 then also sum will be 0.

[@araragikoyomi7186]

When will I able to think the solutions of this types of problem by myself I practiced so much questions then too I didn't able to solve this on my own. But I like your approach I and got the intuition.

[@aditikajale8514]

Can we just take count of 0 1 2 in map?

[@souravjha8244]

can you tell me how to implement the delta function for an equal number of 0s and 1s or any other method is there to find an equal number of 0s and 1s??
