- Write a function
spinWords
that takes in a string of one or more words, and returns the same string, but with all five or more letter words reversed. Strings passed in will consist of only letters and spaces. Spaces will be included only when more than one word is present.
spinWords("Welcome") // "emocleW"
spinWords("Hey fellow warriors") // "Hey wollef sroirraw"
spinWords("This is a test") // "This is a test"
spinWords("This is another test") // "This is rehtona test"
- Write a function
persistence
that takes in a positive parameter num and returns its multiplicative persistence, which is the number of times you must multiply the digits in num until you reach a single digit.
persistence(39) === 3 // because 3*9 = 27, 2*7 = 14, 1*4=4
persistence(999) === 4 // because 9*9*9 = 729, 7*2*9 = 126, 1*2*6 = 12, 1*2 = 2
persistence(4) === 0 // because 4 is already a one-digit number
I am so sorry about my spelling! I am typing on my phone and not my computer so it is really hard, lol.
