Cisco Technical Test Coding Questions with Solutions
Question 1 : Coin Game
Raman was playing a game, he starts with x coins. Now in every step, he wins and loses and he has to get the money or pay the money as needed. He came in contact with a psychic who can see the future and the Psychic predicted the outcomes after each step. Now Raman wants to start the game with the minimum wage where he doesn’t run out of money. Help Raman to find what money he should start with. The only rule to keep playing is not going in a credit situation.
Input Format:
- First line with n, number of steps in the game
- Next n lines, n integers denoting outcomes of every game. Positive means winning and negative means losing that money.
Output Format:
- One single integer denoting the minimum amount to start with
Constraints:
- Number of steps<=10^9
- -1000<=Money needed in each step<=1000
Sample Input:
4
2
-9
15
2
Sample Output:
7
Explanation:
If he starts with 7 rupees, then after steps : 7 ->9 -> 0-> 15 -> 17.

Question 02 : Device Name System
Problem statement: Rocky is a software engineer and he is creating his own operating system called “myFirst os”. myFirst os is a GUI (Graphical user interface) based operating system where everything is stored in files and folders. He is facing issues on creating unique folder names for the operating system . Help rocky to create the unique folder name for it’s os.If folder name already exists in the system and integer number is added at the name to make it unique. The integer added starts with 1 and is incremented by 1 for each new request of an existing folder name. Given a list of folder names , process all requests and return an array of corresponding folder names.
Example
- n=5
- foldername= [‘home’ , ‘myfirst’ ,’downloads’, ‘myfirst’, ‘myfirst’]
- Foldername[0] = ‘home’ is unique.
- Foldername[1] = ‘myfirst’ is unique.
- foldername [2] =’downloads’ is unique.
- Foldername[3] =’myfirst’ already exists in our system. So Add1 at the end of the folder name i.e foldername[3] =”myfirst1″
- Foldername[4 ]=’myfirst’ also already exists in our system.So add 2 at the end of the folder name i.e. foldername[4]=”myfirst2″.
Function description
- Complete the function folderNameSystem In the editor below
- folderNameSystem has the following parameters
- string foldername[n]: an array of folder name string in the order requested
Returns:
- String[n]: an array of strings usernames in the order assigned
Constraints
- 1<=n<=10^4
- 1<=length of foldername[i]<20
- foldername[i] contains only lowercase english letter in the range ascii[a-z]
Input Format:
- The first line contains an integer n , denoting the size of the array usernames Each line i of the n subsequent lines (where i<=0<=n) contains a string usernames[i] representing a username request in the order received.
Sample case 0
- 4
- home
- download
- first
- first
Sample Output 0
- home
- download
- first
- first1
Explanation 0
- foldername[0] = ‘home’ is unique
- foldername[1]=’download’ is unique
- foldername[2]= ‘first’ is unique
- foldername[3]=’first’ is already existing . so add 1 to it and it become first1

Question 3 : Coloured Zenga
Problem Statement :
Rahul is playing a game, wherein he has multiple coloured wooden blocks, stacked one above the other, his task is to remove all the wooden blocks from the stack, without letting it fall and in the minimum number of steps. He can remove one block of a colour at a time, but he can remove multiple blocks of the same colour together. Determine the minimum number of steps in which he can perform this task.
For example, if you remove [red,red] from (white,red,red,white), the resulting array is [white,white].
Note- there are only two colour blocks – red and white
Function description :
Complete the minMoves function in the provided editor. It contains the following parameters:
Parameters:
| Name | Type | Description |
|---|---|---|
| N | Integer | No. of Wooden blocks |
| Array[ ] | Integer Array | Array of Blocks. |
Input format :
The first line contains an integer n denoting the number of blocks. Each n line denotes the colour of the wooden block .
Constraints :
1<=n<=700
0<=a[i]<=1
Sample input 1 :
4
red
white
white
red
Sample Output 2 :
2
Explanation :
Remove [white,white] first The array will be [red,red] The remaining numbers can be removed in one strap .
Sample Input 1:
4
white
red
white
red
Sample Output 1:
3
Sample Explanation:
0
The steps are [white,red,white,red]->[red,white,red]->[red,red]->[]. Therefore the answer is 3.

Question 5 : Seating Arrangement in Exam Hall
Problem Statement :
Semester exams are going on for university students. Examiners noticed that a group of people are trying to cheat. They marked students of that group as ‘1’ and students of another group ( who are not cheating ) as ‘0’
We can reduce cheating by not allowing students from group 1 to sit together, means no two students from group 1 can sit together. Seatings are marked using above conditions. Your task is to give the seating placement of nth possibility Possibility order from 1 to 10 is given below

Sample input :
3 → number of test cases
4
6
9
Sample output :
101
1001
10001
Explanation :
4th possibility is 101
6th possibility is 1001
9th possibility is 10001
