Count Encodings

1. You are given a string str of digits. (will never start with a 0) 2. You are required to encode the str as per following rules 1 -> a 2 -> b 3 -> c .. 25 -> y 26 -> z 3. You are required to calculate and print the count of encodings for the string str. For 123 -> there are 3 encodings. abc, aw, lc For 993 -> there is 1 encoding. iic For 013 -> This is an invalid input. A string starting with 0 will not be passed. For 103 -> there is 1 encoding. jc For 303 -> there are 0 encodings. But such a string maybe passed. In this case print 0. Input Format A string str Output Format count of encodings Constraints 0 < str.length <= 10 Sample Input 123 Sample Output 3 Solution: import java.io.*; import java.util.*; public class Main { ...

Count A+b+c+ Subsequences

1. You are given a string str. 2. You are required to calculate and print the count of subsequences of the nature a+b+c+. For abbc -> there are 3 subsequences. abc, abc, abbc For abcabc -> there are 7 subsequences. abc, abc, abbc, aabc, abcc, abc, abc. Input Format A string str Output Format count of subsequences of the nature a+b+c+ Constraints 0 < str.length <= 10 Sample Input abcabc Sample Output 7 Solution: import java.io.*; import java.util.*; public class Main { public static void main(String[] args) throws Exception { Scanner sc = new Scanner(System.in); String str = sc.nextLine(); int counta = 0, countb = 0, countc = 0; for(int i=0;i<str.length();i++){ char ch = str.charAt(i); if(ch == 'a') ++coun...

Basics of Java | Operators | Day 1

Problem: Operators are symbols that perform operations on variables and values. For example, + is an operator used for addition , while * is also an operator used for multiplication . Operators in Java can be classified into 6 types: Arithmetic Operators Assignment Operators Relational Operators Logical Operators Unary Operators Bitwise Operators References: Click Here . We will discuss about arithmetic operators and rest you can study from the references mentioned above. Arithmetic Operators: Arithmetic operators are used to perform arithmetic operations on variables and data. For example, a + b; Here, the + operator is used to add two variables a and b. Similarly, there are various other arithmetic operators in Java. Operator Operation + Addition - Subtraction * Multiplication / Division % Modulo Operation (Remainder after division) Task: You are given two integers as input a and b You need to perform several...
