20. An array of size 5X5 is given to us. The elements from 1 to 25 are to be inserted in the array, such that starting from a particular position for an element i, the next element i+1can be inserted only at the mentioned positions (u,v), and if these all positions are occupied then it returns giving a count of how many positions have been occupied in the array:
(u,v) = (x+/-3 , y)
(u,v) = (x , y+/-3)
(u,v) = (x+/-2 , y+/-2).

Programmin section 1.30 hrs 4 question.
1)Seat Planing 
Write a function for seat allocate and seat reserved.Seat allocate array and seat reserver array.Seatallocate array is of 10*20 and each row and column represent A1,A2....;B1,B2.....;........J1,J2... andso on i.e row are A to J whereas col starts from 0 to 19.Each cell in the table represent either 0 or1. 0 rep seat available , 1 repr seat reserved. Seat allocation starts from highest to lowest.And row j is highest, i is second highest and so on.Max 20 seats can be booked at a time. if seat is available print the seat no like "B2" i.e (2 row, 3 col)and seat is booked." otherwise Print "Seat is not available."

eg.: INPUT: AEGBCNAVNEETGUPTAEDAGPE
OUTPUT:
E
or

Whole Testpaper Pce, Jaipur - 19 February 2009 NAGARRO 19th FEBRUARY AT JAIPUR 
Hello Friend, Ajay Here. I just decribing here at Paper Procedure Which held at PCE, Jaipur on 19 feb.2009, Mainly for nagarro Selecton procedure 3 round conduct
In Round first.
40 Question in 90 minutes. 
There Mainly two Section.
Apptitude Section:-
Apptitude Section there was 40 question 
This Section divide in two part.
1) Mathematics part:-(20 Question) Trignometry, Profit and loss,Ven disgram,Sphere, Trinagle problems
Some Question in Mathematic was such as
1) if Sec^2 A= 4xy/(x+y)^2
Ans:- This is possible only for x=y; 

2)if SecA*SinA=0 then what will be the Value of CosA.
Ans:- CosA=Cos0=1

Side. 

7) Two question based on ven diagram. 

8) One Question on profit and loss such as if a shopkeeper sell 960 gm sugar in respect of 1000g at same price then what will there profit .Ans:- 25/6 

9) How Many no. Between 1000 to 9900 in which four digits of number are different. 

10) if xy = 6 and x^2y+xy^2+x+y = 9 then find out the Value of x^2 + y^2 


2) Reasonong Part:- Mainly there was four question and each question divided in 5 Sub Question 
1) First Question was base on Blood relation . it was such that if A, B, C, D, E, F, have relation with J as Father, Brother, Daughter, Aunt , Mother, Wife Unorderly and there was given condition such as 
1) A and B have not same Sex 
2) D, E have Same Sex 
3) E born Before A. 
Then Find out the following Answer. 

2) Second Question was based on A Contract. 
These All question from R.S. Agarrwal. So Please refer them for Practice because it is Very time
Consuming Part. 
Technical Paper:-
Second Paper of Round 1 total Technical. There Was four Question one Quest ion i Remember was
such as 
Q.1 A string of charater is given.Find the Continous Occurance of a character and display that
character.
eg.: INPUT: AAAAAAEGBCNAVNEETGUPTAEDAGPE
OUTPUT:
A or if Same then A and D. 
Q.2 One question was base on Hash Table related Teacher, Their topic,in A 20 days Period. 
Q.3 Based on link list where one pointer Point the Next Node and Second Show their Sub Node. 

Towrite a Fuction Which Return the largest integer Value. 

Second part
1.a function input(int[] array) was given and we had to enter any number and the entered no./should convert into absolute no like 4578, 6789 , 1234 etc means the no should convert into/incresing nos.
2.A mXn matrix was given and rows and coloumn were sorted as shown below then we had to/write a function that search a desired entered no in the matrix .with minimum complexity
1 2 3 4
5 6 7 8
9 10 11 12
13 14 15 16
3.There is a array of 99 cells and we have to enter 1-100 elements in it , no two elements wouldrepeat , so the is one no. missing because 99 cells and 1-100 nos. sowe had to implement a function to find that missing no.
