coding interview questions
Q #1) How can you reverse a string?
Answer: String is reversed with the following algorithm:
- Initiate
- The string which is to be reversed is declared.
- Get the length of the string.
- Start a loop and then swap the position of the array elements.
- Keep the exchanged positions.
- Print the reversed string.
Q #2) What is a palindrome string?
Answer: After the string is reversed as discussed in Q #1, we need to put the following condition:
Code snippet:
if(actualtxt.equals(reversetxt)){ return “Palindrome”;else return “Not Palindrome”;} |
Thus palindrome string is the one which on reversing remains the same, for example, – ‘madam’ is a palindrome string.
Q #3) How to get the matching characters in a string?
Answer: To get the matching characters in a string, the below steps are followed:
- Hash Map data structure is taken which works with the key-value pair.
- Loop the strings, character by character, and verify if that character of the string exists in the hash map or not.
- If the result is true, the counter for the character in the hash map is increased or else then put a count as 1.
- Once the loop ends, then the Hash map is traversed and print the characters with more than 1 count.
Code snippet:
HashMap<Character, Integer> mp = new HashMap<> (); for (int j = 0; j<text.length (); j++) { char ch = text.charAt(j); if(mp.containsKey(ch)){ int cnt = mp.get(ch); mp.put(ch, ++cnt); }else{ mp.put(ch, 1); }}Set<Character> charct = map.keySet(); for (Character ch: charct){ int c= mp.get(ch); if(c>1){ System.out.println(ch+ " - " + c); }} |
Q #4) How to get the non-matching characters in a string?
Answer: To get the non-matching characters in a string, the below steps are followed:
- Hash Map data structure is taken which works with the key-value pair.
- Loop the string, character by character, and verify if that character of the string exists in the hash map or not.
- If the result is true, the counter for the character in the hash map is increased or else then put a count as 1.
- Once the loop ends, then the Hash map is traversed and print the characters with a count equal to 1.
Code snippet:
HashMap<Character, Integer> mp = new HashMap<> (); for (int j = 0; j<text.length (); j++) { char ch = text.charAt(j); if(mp.containsKey(ch)){ int cnt = mp.get(ch); mp.put(ch, ++cnt); }else{ mp.put(ch, 1); }}Set<Character> charct = map.keySet();for (Character ch: charct){ int c= mp.get(ch); if(c==1){ System.out.println(ch+ " - " + c); }} |
Q #5) How to calculate the number of vowels and consonants in a string?
Answer: To calculate the number of vowels and consonants in a string, the below steps are followed:
- Get the string on which count has to be performed.
- Run a loop from 0 to the length of the string.
- Take a single character at a time and verify if they are a part of the group of vowels.
- If the result is true, increase the count of vowels or else increment the count of consonants.
Code snippet:
for (int k = 0; k < text.length(); k++) { char c = text.charAt(k); if (c == 'a' || c == 'e' || c == 'i' || c == 'o' || c == 'u') owls += vowlselse consonts += consonts}System.out.println("Vowel count is " + vowls); System.out.println("Consonant count is: " + consonts); |
