in C why you use k+1 ? if we have to erase 3 number then why you take k+1 ? it will get the minimum of 4 erasing numbers, nah?

Yes...you are correct. The loop actually goes till k only. In my template I have defined fr(i,j) to go from i to j-1. Sorry for the confusion.

@@lessonsoflife8835 but bro when i go for (i=0 ; in>>k; vectorv(n) ,pre(n); mapmp; f(int i=0 ,i>v[i]; } vsort(v) ll mn = inf ; forint i=0 ,i

@@lessonsoflife8835 ok ! but when i just iterate till k i got wa int mn = inf ; for(int i=0 ;i

@@lessonsoflife8835 ok ! but in my code I do the same approach . go till k but got WA .. can you tell me why ? but when i go till k+1 its accepted.
