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)

superb

[@user-vi5nd3pl8s]

also make a video on special array 2

yaa yaa, it is already live on channel ❤️

#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

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??

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 🤘

[@meme_Overflow]

4 saal to bahut dur ki bat h keep hoping

[@YuvikaSingh-gs2sj]

[@ARYANMITTAL]

Done sir, already live on channel ❤️

[@shravankhar7180]

Can anyone explain why we should divide by 2

[@TON-108]

repetitions bro,
