Question

In Java

Create a 2D 10x10 array of Characters named UPPERCASE containing an uppercase character in each cell. Next, traverse the array and determine if any rows contain both ‘X’ and ‘R’. If a row does contain both, return true, else return false once you have traversed the entire array

Answer 1

//TestCode.java
public class TestCode {
    public static boolean traverse(char[][] UPPERCASE){
        boolean hasR, hasX;
        for(int i = 0;i<UPPERCASE.length;i++){
            hasR = false;
            hasX = false;
            for(int j = 0;j<UPPERCASE[i].length;j++){
                if(UPPERCASE[i][j]=='R'){
                    hasR = true;
                }
                else if(UPPERCASE[i][j]=='X'){
                    hasX = true;
                }
            }
            if(hasR && hasX){
                return true;
            }
        }
        return false;
    }
    
    public static void main(String[] args) {
        char UPPERCASE[][] = new char[20][20];
        
        // Function call
        System.out.println(traverse(UPPERCASE));
    }
