3 Amazing Firefox Hack

  1.Save Session For All Tabs Opened In Multiple Firefox Windows:

If you are an ardent user of Firefox then you may be aware that when more than one Firefox windows are opened up, in that case when you close a Firefox window, it does ask me the option to save the session and exit, rather it ask to close all the tabs in that Firefox window, but it won’t save the tabs in other windows.

Question:
http://uva.onlinejudge.org/external/104/10424.html

Solution:
1. Take 2 strings input. adjust the values of each character according to the problem describes. (here it was stored in ans1 and ans2 variables)
2. Then make the sum of these numbers until it comes in one digit. (here it is done in temp1 and temp2 variables)
3. Answer the value of the two ratio in percentage for the larger value of temp1 and temp2.

UVA Problem#10347

Question:

http://uva.onlinejudge.org/external/103/10347.html

Solution:

It's a bit tricky to derive the formula for this problem. Basically, you can prove that the area of the triangle formed by the medians is 3/4 of the area of the original triangle. Then, you can use Heron's formula to get the area of the median triangle, and multiply by 4/3. So in all:

A = (4/3) * sqrt(s(s-m1)(s-m2)(s-m3))

Where m1, m2, and m3 are the median lengths, and s is the semiperimeter of the median triangle:

s = (m1 + m2 + m3) / 2

There are some tricky things to watch out for:

3. Print the 2nd value from the array.

UVA Problem#10346

Question:
http://uva.onlinejudge.org/external/103/10346.html 

Solution:

Find the pattern and derive the following formula (total_cigar and butt initally set to 0) and simply simulate the process...

while (n > 0) {
  total_cigar += n; /* accumulate all new cigars so far */
  butt += n; /* after Peter smokes these n cigar, we have n butts */
  n = butt / k; /* so these n butts become new cigars */
  butt %= k; /* butts left are reserved for future cigars */
}
