how many integers are there between 10000 and 99999 in which all digits are different? How many two-digit numbers can be made using the digits 1 through 7 if the digits can be repeated? How many 5 digit numbers can be found from the digits 0,1,2,3,4,5,6,7, 8 if...
Given the digits (0, 1, 2, 3, 4, 5, 6, 7, 8, 9), how many 5 digit numbers can be made with different digits? Fundamental Principle of counting the fundamental principle of counting gives the total number of ways to do a particular task....
For example, each of the following five-digit integers are palindromes: 12321, 55555, 45554 and 11611. Write a program that reads in a five-digit integer and deter- mines whether or not it is a palindrome. [Hint : Use the division and remainder operators to separate the number into its...

function splitByMany( manyArgs, string ) { do { let arg = manyArgs.pop() string = string.replace(arg, manyArgs[0]) } while (manyArgs.length > 2) return string.split(manyArgs[0]) } So, in your case, you could then call let array = splitByMany([" ", ","], 'My lo...
Palindromes: A palindrome is a word or phrase that reads the same forwards and backwards. The cryptic part of the clue will generally just clue you in that it is a palindrome. (In the explanation, this will be marked with > and < symbols.) ...
