Zoho Interview Coding Questions

For freshers, they mostly ask programming questions based on an array, string, and Linked lists. To crack this round, check data structure and interview coding questions. Practicing these coding questions helped me to crack this round.

Coding Question 1: Based on String

Input: a1b2c3
Output: abbccc
Caution: Don't use inbuilt functions

Explanation:

• After we have the number 1 so a repeats one time = a
• After b we have the number 2 so it repeats two times = bb
• After c we have the number 3 so it repeats three times = ccc
• Final Output: abbccc

Algorithm:

• Start the Program
• Get the input as a single string
• Loop through the entire string to find the numbers
• After finding the number, Repeat the previous character the same number of times
• For example a4 ( So you find the number 4 and print a 4 times)
• Follow the steps 3,4 for the entire string
• End the Program

C Program

Prerequisite:

• basic data types in C
• loop statement in C

Code:

#include<stdio.h>
int main()
{
  char str[100]="a1b2c4";
  int len=0;
  while(str[length]!='\0')
    len++;
  for(int i=0; i<len; i++)
  {
    if(str[i]>'0' && str[i]<'9')
    {
      int num=str[i]-'0';
      for(int j=0; j<num; j++)
      {
        printf("%c", str[i-1]);
      }
    }
  }
}

Output:

abbcccc

Python Program

If you know the Python basic syntax, you can implement the same program in Python in very few lines of code. That’s the beauty of Python programming.

Prerequisite:

• range() function in Python
• Python for-loop

Code:

msg="a1b2c4"
out = ""

for ind in range(0, len(msg), 2):
  out += (msg[ind] * int(msg[ind+1]))

print(out)

Output:

abbcccc

Coding Question 2: Based on the Array

Input: [2,1,0,-8,-9]
Output: 0.4 , 0.2 , 0.4

Explanation:

• First, find the total number of elements in the array = 5
• Find the total number of positive numbers=2
• Find the total number of neutral numbers=1
  (0 is the only neutral number)
• Find the total number of negative numbers=2
• Output = [ (no of positive number/length of array), (no of neutral numbers/length of array), (no of negative numbers/length of array) ]
  =[⅖, ⅕, ⅖]
  =[0.4, 0.2, 0.4]

Algorithm:

1. Start the Program
2. Get the input as an array
3. Find the length of the array
4. Find the number of positive, neutral, and negative numbers
5. Divide each one of the above results with the length of the array and print the output as an array( Make sure you print the output in float format and use 0.1f for one precision)
6. Stop the program

C Program

Here we are using sizeof() operator.

#include<stdio.h>
int main()
{
  int a[]={1,2,4,-8,-1,0};

  int n=sizeof(a)/sizeof(int);
  int np, nz, nn;
  for(int i=0; i<n; i++)
  {
    if(a[i]>0)
    {
      np++;
    }
    else if(a[i]<0)
    {
      ne --;
    }
    else
    {
      nz++;
    }
  }
  printf("%0.1f , %0.1f , %0.1f ", np/n, nz/n, nn/n);
  return 0;
}

Output:

0.6 , 0.2, 0.4

Python Program

Let’s solve the same question in Python programming.

list_data =  [2,1,0,-8,-9]

count_positive = 0
count_neutral = 0
count_negative = 0
length_arr = len(list_data)

for val in list_data:
  if val>0:
    count_positive += 1
  elif val<0:
    count_negative += 1
    else:
      count_neutral += 1

print(
  count_positive/length_arr, 
  count_neutral/length_arr, 
  count_negative/length_arr
)

Output:

0.4 0.2 0.4

There can be multiple types of coding questions asked based on the string, array. If you get the basics, you can solve these coding challenges in C/C++, Java, Python, or any programming language of your choice.

Also, check the technical interview coding questions asked in Zoho for freshers (based on experience shared by the candidate).
