Help with Java function.
Suppose I have a string input that contains letters followed by numbers. Can someone write a function that only returns the number values?
Ex: Input "dog12" should return 12. Edit: It should return 12 as an integer.

public static int parseNumbers(String str){
String temp = "";//Temporary empty string to store only
digits
for(char ch : str.toCharArray()){
if(Character.isDigit(ch))//Check if character is digit or not
temp += ch;//If yes, then add it to temporary string
}
return Integer.parseInt(temp);//Convert string to int and
return
}

Define a function num_letters(...) that evaluates a string consisting of numbers, letters, and symbols that returns the total number of letters of the alphabet (upper and lowercase) in the string. If there are no letters in the function, then it should return the message "no way". As an example, the following code fragment: st1="aihj{234][o" print (num_letters(st1)) should produce the output: 5

Write an LC-3 program (starting at memory location 0x3000) to take a string as input and then output information about this string. The end of the string will be denoted with the "#" character. Once the "#" has been found, output the following in order: 1) The letter “u” followed by the number of uppercase letters in the string (A-Z) 2) The letter “l” followed by the number of lowercase letters in the string (a-z) 3) The letter “n” followed...

Write MIPS code that converts a string containing a number into an actual number. The function to do this conversion, atoi (Array To Integer) should have a single input (the string) and output a single number (the integer). The Java/C code is as follows: atoi(a0: array) { int digit, number, i = 0; while( (array[i] >= '0') && (array[i] <= '9') ) { digit = array[i] - '0'; number = 10 * number + digit; i++; } return number; }

Write a function with two input parameters: an array of numbers and the size of the array (the number of elements). The function should return the count of even numbers in the array. For example, if the input to the function is the array [3, 2, 45, 56, 12], the function would return the integer 3. Use the following function header: int countEvens(int nums[], int size) { }

Python help! Any help is appreciated, thank you! Fill in the missing function, monthString(), in the program. The function should take number between 1 and 12 as a parameter and returns the corresponding month as a string. For example, if the parameter is 1, your function should return "January". If the parameter is 2, your function should return out "February", etc. def monthString(monthNum): """ Takes as input a number, monthNum, and returns the corresponding month name as a string. Example:...
