Please I need help. Java language

  1. Method name: getScores
    Return value is a String of numbers scaled so that the highest number in the parameter String becomes 100 and all the other numbers are moved up by the same amount. This String should also be numbers separated by spaces with no additional characters. The order of the numbers should stay the same, so that a number in the original string has the equivalent scaled number in the returned string in the same place.
    Example: curveScores("45 85 90 80 30") would return "55 95 100 90 40".

Answer #1

import java.util.Arrays;

public class Main {

public static String curveScores(String str){

String tokens[] = str.split(" ");

int max = -1, index = -1;

for(int i=0; i<tokens.length; ++i){

if(Integer.parseInt(tokens[i]) > max){

max = Integer.parseInt(tokens[i]);

index = i;

}

}

int diff = 100 - max;

for(int i=0; i<tokens.length; ++i){

int num = Integer.parseInt(tokens[i]);

if(i != index)

num = num + diff;

else

num = 100;

tokens[i] = num+"";

}

return Arrays.toString(tokens);

}

public static void main(String[] args) {

System.out.println(curveScores("45 85 90 80 30"));

}

}

    1.Method name: findSmallestPositiveNumber Parameter(s): A String containing integer numbers separated by spaces. There must be at least one positive number in the String. Return value: An int value that is the smallest number greater than 0 in the input string. Example: findSmallestPositiveNumber("2 -4 5") should return 2. Note: Even though I put this first, I would consider working on this later. The other methods are basically just applying the patterns we looked at in class. This one is similar but...

    Language: Python Function name : findwaldo Parameters : string Returns: int Description: Write a recursive function that takes in a string containing some combination of letters, numbers, and spaces, and return the starting index of the first instance of “waldo” contained in that string. If the string does not contain “waldo”, return -1. This function IS case sensitive, so “waldo” is not the same as “WALDO”. Code using string functions such as .index() and .find() that oversimplify the problem will...
