AnswersThe King's Land Sale - 2

- sunilkanaujia.manit in India

You might have seen shopkeepers offering sale on their trade items to promote their business - like sale on electronic gadgets or sale on clothing and accessories etc. But have you ever come across something like sale of land ?

Yes, the king of Byteland has grown old and wants to sell away his territory as soon as possible. So he announced a sale on his plot. This drew attention of many land lords and everybody hurried to buy land at the cheapest prices. The king had declared that he would accept bids of only rectangular plots and one needs to mention the diagonally opposite corners(a, b) and (c, d) of the land he wishes to buy. They would write these 4 numbers (a, b, c, d) on a piece of paper, seal it in an airtight envelope and give it to the king.

The king received N such envelopes. As the process was hidden there were many envelopes containing plot descriptions that shared some (or even all) common area. The king now wants to know the union of the areas of all plots that have come under the bidding.

Note that the rectangles made by the plots are always aligned to the rectangular axes, their areas is always positive and c >= a and d >= b.

Note that the rectangles made by the plots are always aligned to the rectangular axes, their areas is always positive and c >= a and d >= b.

Constraints

1 ≤ T ≤ 20

1 ≤ N ≤ 20

-10000 ≤ a, b, c, d ≤ 10000

Input

The first line of the input contains the number of test cases T. The description of T test cases follow. Each test case starts with a line containing an integer N, the number of rectangular plots. Then N lines follow, each with 4 space separated integers, a b c d,(a, b) and (c, d) representing the diagonally opposite corners of the plots.

Output

For each test case print one line, the union of the areas of all the plots.

Explanation

1) The individual areas of both plots are 4 each. But they share a common area of 1 between them (between (1, 1) and (2, 2)). Therefore the total area is 4 + 4 - 1 = 7

2)Both the plots of no area in common. So we simply add their individual areas (6 + 9 = 15).| Report Duplicate | Flag | PURGE

AnswerGiven N natural numbers A1, A2, A3 . . . AN, you have process Q queries of following two types:

- sunilkanaujia.manit in India

1 i j: Perform the operation Ai = j.

2 L R: Print the LCM of the elements AL, AL+1, AL+2 . . . AR.

Here LCM stands for lowest common multiple. Please help Shil to open the lock.

Input

First line will contain integer N.

Second line will contain N natural numbers denoting array A.

Third line will contain number of queries Q.

Then next Q lines will contain either query of Type 1 or 2.

Output

For each query of Type 2 output the required answer. Since LCM can be very large output it modulus 109+7.| Report Duplicate | Flag | PURGE

AnswersCount Scorecards

- sunilkanaujia.manit in India

In a tournament, N players play against each other exactly once. Each game results in exactly one player winning. There are no ties. You have been given a scorecard containing the scores of each player at the end of the tournament. The score of a player is the total number of games the player won in the tournament. However, the scores of some players might have been erased from the scorecard. How many possible scorecards are consistent with the input scorecard?

Input Format

The first line contains the number of cases T. T cases follow. Each case contains the number N on the first line followed by N numbers on the second line. The ith number denotes s_i, the score of the ith player. If the score of the ith player has been erased, it is represented by -1.

Output Format

Output T lines, containing the answer for each case. Output each result modulo 1000000007.

Constraints:

1 <= T <= 20

1 <= N <= 40

-1 <= s_i < N

Sample Input:

5

3

-1 -1 2

3

-1 -1 -1

4

0 1 2 3

2

1 1

4

-1 -1 -1 2

Sample Output:

2

7

1

0

12

Explanation:

For the first case, there are 2 scorecards possible: {0,1,2} or {1,0,2}.

For the second case, the valid scorecards are {1,1,1}, {0,1,2}, {0,2,1}, {1,0,2}, {1,2,0}, {2,0,1}, {2,1,0}.

For the third case, the only valid scorecard is {0,1,2,3}.

For the fourth case, there is no valid scorecard. It is not possible for both players to have score 1.

For the fifth case, 6-variations of {{3,1,0}[2]}, 3 variations each of {{2,2,0}[2]} and {{2,1,1}[2]}

Max Score: 89pts dynamic

AnswersThe below Java program prints the numbers from 1 to 50. But for multiples of three print "DNA" instead of the number and for the multiples of five print "RNA". For numbers which are multiples of both three and five print "ATGC". Please identify the three bugs in the code and suggest how they can be resolved.

- sunilkanaujia.manit in India

public class SeqTest {

public static void main(String args[]) {

for(int i = 1; i <= 50; i++) {

if(i % 3 == 0) System.out.println("DNA");

else if(i % 5 == 0) System.out.println("RNA");

else if(i % (3+5) == 0) System.out.println("ATGC");

else System.out.println(“1 to 50”);

}

}
