actuall top-notch explanation, thank you man!

[@satviksrinivas8764]

Thank you!

Hello for the second loop can it also be done knowing the fact there are two 6 at the 3rd position and 4 is the number of elements in the array, so why not just do 2*(4 - 2) = 4 directly, and then for all the places this way the second loop will just take O(digits of the number in nums)

#define ll long long int class Solution { public: unordered_map mp; void count(int el){ string s = to_string(el); for(int i=0; i

You're so smart , love ya bro keep it up!

[@AleemPasha-r2w]

also make a video on special array 2

[@ARYANMITTAL]

yaa yaa, it is already live on channel ❤️

[@shravankhar7180]

Can anyone explain why we should divide by 2

[@TON-108]

repetitions bro,

[@shatulbansal4756]

Bro, you made a small mistake in TC calculation, length of each number is upto 10^9 and not 10, so TC of your solution will be more than what you suggested, your views??

[@hello-world8906]

so wont the TC be O(n*m), where n is the number of elements and m is the number of digits (which can be 10^9 in worst case)? and why isn't this causing TLE then?

Maine yr BC map ka ni socha par maine modulo se karke har pair k liya check kiya koina pehla contest tha abhi toa 1st sem start bhi ni hua,baki koi advice do guys 🤘
