Duration: 1 hour
Total Questions: 30

Round: Test
Experience: The three questions are of three different levels.

1. You will be given two numbers. The first one is the starting point and the second one is the ending point of a range of integers. You have to count the number of integers in that range which are divisible by the first number.

Ex : INPUT : 3 18
OUTPUT : 6

2. You will be given a number. You have to find the sum of the digits. If the sum exceeds 9, you have to add the digits of the sum recursively until you a get a single digit sum.

EX : INPUT : 9999
OUTPUT : 9

Explanation: 9999 => 9 +9+9+9=36 => 3+6 =9

3. You will be given an array of characters which include ( L, R , or a number in the range '0' to '9'). A ball is kept on a line of integers initially kept at zero. The ball has to execute the instructions sequentially as follows:
(i) If an 'L' character is encountered, the ;position of the ball has to be decremented.
(ii) If an 'R' character is encountered, the position of the ball has to be incremented.
(iii) If an integer (in the range '0' to '9) is encountered , we have to go to that index in the array and execute the instruction present in that index.

Finally, after all the instructions are executed, you have to print the final position of the ball.

EX : INPUT :
Number of instruction : 5
Instructions: LR1R2

OUTPUT : 3

Explanation :
(i) Initially, the ball is at 0. Since the 0th index in the array is 'L' , the ball moves to 0-1= -1 position.
(ii) The 1st index is 'R' hence, the position of the ball is -1 +1 = 0 position.
(iii) The 2nd index is '1', hence we have to go to index 1 in the array which is 'R', hence the new position is 0+1 =1.
(iv) The 3rd index is 'R', hence the new position is 1 +1 =2.
(v) The 4th index is '2' , hence we have to go to 2nd index is '1' , hence we have to go again to 1st index , which is 'R' hence the final position is 2+1 =3.

Tips: We need to solve all the three the problems to have better chances of clearing this round.
