Problem: Count substrings starting with a vowel in a given string, modulo 10003. Solution: public class Solution { public int solve(String A) { int count = 0; char vowels[] = {'a', 'e', 'i', 'o', 'u', 'A', 'E', 'I', 'O', 'U'}; ...
Question: Given two strings A and B, check if they can be rearranged to match (i.e., check if they are permutations of each other). Solution: import java.util.Arrays; public class Solution { public int permuteStrings(String A, String B) { ...
Strings are a fundamental data type in Go, and they are crucial for any programming language as they allow you to work with text data. In Go, strings are immutable sequences of bytes, meaning that once a string is created, it cannot be modified. Howe...
