Given with temperature ‘n’ in Celsius the challenge is to convert the given temperature to Fahrenheit and display it.ExampleInput 1-: 100.00 Output -: 212.00 Input 2-: -40 Output-: -40For converting the temperature from Celsius to Fahrenheit there is a formula which is given belowT(°F) = T(°C) × 9/5 + 32Where, T(°C) is temperature in Celsius and T(°F) is temperature in FahrenheitApproach used below is as followsInput temperature in a float variable let’s say CelsiusApply the formula to convert the temperature into FahrenheitPrint FahrenheitALGORITHMStart Step 1 -> Declare a function to convert Celsius to Fahrenheit void cal(float cel) ...

Let’s say we have set out inut string in myStr variable. Now loop through until the length of string and check for alphabets with ASCII values −for (int i = 0; i < myStr.length(); i++) { char c = myStr.charAt(i); if (!(c >= 'A' && c = 'a' && c = 'A' && c = 'a' && c
At first, convert the string into character array. Here, name is our string −char[] ch = name.toCharArray();Now, loop through and find whether the string contains only alphabets or not. Here, we are checking for not equal to a letter for every character in the string −for (char c : ch) { if(!Character.isLetter(c)) { return false; }Following is an example to check if a string contains only alphabets using RegexExample Live Demopublic class Main { public static boolean checkAlphabet(String name) { char[] ch = name.toCharArray(); for (char c : ch) { ...

Let’s say our string is −String str = "Amit123";Now, using allMatch() method, get the boolean result whether the string has only alphabets or now −boolean result = str.chars().allMatch(Character::isLetter);Following is an example to check if a string contains only alphabets using Lambda Expressions −Exampleclass Main { public static void main(String[] args) { String str = "Amit123"; boolean result = str.chars().allMatch(Character::isLetter); System.out.println("String contains only alphabets? = "+result); } }OutputLet us see another example with a different input −String contains only alphabets? = falseExampleclass Main { public static void main(String[] args) ...

Given with n nodes the task is to print the product of all the nodes of a singly linked list. The program must traverse all the nodes of a singly linked list starting from the initial node till the NULL is not found.ExampleInput -: 1 2 3 4 5 Output -: 120In the above example, starting from first node all the nodes are traversed i.e 1, 2 3, 4, 5, 6 and their product is 1*2*3*4*5*6 = 120Approach used below is as followsTake a temporary pointer, lets say, temp of type nodeSet this temp pointer to first node which is ...
