### 11599 - Triangle and Polynomial

Ok, I figured out the exact value of x (say a). But I am not sure how to compute the polynomial. One way I thought of was have a generic polynomial of degree n, say f(x) = x^n + x^n-1 + x^n-2 + .... + 1, then calculate the value f(a) and then adjust the const term. but that way i can't get f(a) = 0 ...

### Re: 11378 - Bey Battle

It would've been nice if the lower value of N was defined. I don't think there were case with N == 1 (haven't tested though, I just printed 0 for that case)

### Re: 11542 - Square

I tried with random generated input and a brute force algo. Although I tried brute force algo with N <= 30, I get correct result from my WA algo as well.

And yes I do shift with 1LL << shiftVal

I see several things that could led to an RE Make the collection word size 81 as you need to give space for the NULl character as well. char palindromeCollection[500][81] int isPalind(char str[]) { int len; char str1[81]; // Change this to 81 as well. len=strlen(str); int i,j; for (i=0,j=len-1; i<j;...

### Re: 11481 - Arrange the Numbers

Whats wrong with my thinking - From first m we need to choose k , thats mCk for remaining m - k positions we can't use the first remaining m - k numbers.. So we fill those positions with from end n - m number. The way we can do that is ( n-m)P(m-k) Now we have remaining n-m positions and n-m numbers...

### Re: 11232 - Cylinder

Got Acc..

I had success with lower eps value (instead of 1e-9 instead of 1e-6).

I think binary search is not at all needed as the max volume can be at the terminal values only. Haven't tried that out yet though.

### Re: 10245 - The Closest Pair Problem

.... d = ((X[i]-X[j])*(X[i]-X[j]))+(Y[i]-Y[j])*(Y[i]-Y[j]); .... if(dist<=10000) printf("%.4f\n",sqrt(dist)); else printf("INFINITY\n"); So dist basically holds the squared distance. in your if condition shouldn't you be doing dist = sqrt(dist); if (dist <= 10000) printf("%.4f\n", dist); else print...
