Technical Ability Test: This was difficult. three questions to be attempted in 60 min. The Coplete Technical Paper was as follows: Write the Pseudo code for the following: 1. Wrie a function which returns the most frequent number in a list of integers. Handle the case of more than one number which meets this criterion. public static int[] GetFrequency(int[] list) 2. Counting in Lojban, an artificial language developed over the last fourty years, is easier than in most languages The numbers from zero to nine are: 0 no 1 pa 2 re 3 ci 4 vo 5 mk 6 xa 7 ze 8 bi 9 so Larger numbers are created by gluing the digit togather.

Where now stands that small knot of villages known as the Endians, a mighty forest once stood. Indeed, legand has it that you could have stoodon the edge of the wood and seen it stretch out for miles, were it not for the trees getting in the way. In one section of the forest, the trees stood in a row and were of hight from 1 to n, each hight occurring once and once only. A tree was only visible if there were no higher trees before it in the row. For example, if the heights were 324165, the only visible trees would have been those of height 3,4 & 6. Write a Program that takes an array of integers representing the heights of the trees in the row as input and prints the list of the visible trees. //////////////////////////////////////////////////////////// //////////////////////////////////////////////////////////// //////////////////////////////////////////////////////////// //////////////////////////////////////////////////////////// ////////////////// Ques1: Given an array containing k nos in the range 1..n and another scratch array of size n.

Write the program to display the result as: Product Month No. of copies A January 12 A February 15 A March 27 B January 54 B February 15 B March 10 C January 37 Ques3: Definition of priority queue was given. We have to implement the priority queue using array of pointers with the priorities given in the range 1..n. The array could be accessed using the variable top. The list corresponding to the array elements contains the items having the priority as the array index. Adding an item would require changing the value of top if it has higher priority than top. Extracting an item would require deleting the first element from the corresponding queue. The following class was given: Ques4: 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: //////////////////////////////////////////////////////////// //////////////////////////////////////////////////////////// //////////////////////////////////////////////////////////// //////////////////////////////////////////////////////////// ////////////////// Example: if the starting element is 1 with the given positions (1,2), then next element 2 can be placed at any one of the positions marked with *. _ _ _ _ _ 1 _ _ _ * _ _ _ _ _ _ _ * _ _ * _ _ _ _ 2. Four questions of programming in c++, questions were:( 1:30 hr) a) Bubble sort through recursion b) Display Pattern: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 … c) Perform the functionality of 2-D array through 1-D array and in it the functions to be performed were: (1) Display the array in 2-D format (2) Display a particular element (3) Display a particular row (4) Display a particular column d) Give an efficient program for string matching like: Text: this is the code in the text which you have to search by code Pattern: Code Count the no. of occurrences of the pattern to be searched //////////////////////////////////////////////////////////// //////////////////////////////////////////////////////////// //////////////////////////////////////////////////////////// //////////////////////////////////////////////////////////// ////////////////// a) suppose u r given a 4*3 rectangle like (take these values from user) Now u have to calculate the no. of squares in this rectangle like: No. of squares of dimension 1 is 12 No. of squares of dimension 2 is 6 No. of squares of dimension 3 is 2 No. of squares of dimension 4 is 0 Total no. of squares are 20. b) Suppose u r given a string. U have to find the occurance of the characters A-Z in that string. Each character must appear in the string and must appear only once. If It that occurs in string more than one time return 1 showing it is a perfect string otherwise return 0 showing it is not a perfect string. c) Suppose u r given 10000 marks. U have to pick up top 20 top marks from them and display it on the screen. (Use the optimal sorting algorithm) d) Suppose u have a chess board. U have to insert 8 queens on the chessboard in the style that the queens don’t intersect in the diagonals, columns and rows. If they intersect return 1 else return 0.(that is no more than one queen should be present either in row or column or diagonals.) If the queen is inserted at a position in the chessboard, its count is 1. 1735
