Question

Days of the week are represented as three-letter strings ("Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun"). Write a javaScript function solution that, given a string S representing the day of the week and an integer K (between 0 and 500), returns the day of the week that is K days later

Answer 1

Answer: function getDay(s, k){

var weekDays = ["Mon","Tue","Wed","Thu","Fri","Sat","Sun"];

var index=weekDays.findIndex(function(weekDay){return weekDay==s;});

return weekDays[(index+k)%7];

Explanation:

//this functions receive the next parameters:

//s which is the day of the week

//k the number of days after s week day

function getDay(s, k){

var weekDays = ["Mon","Tue","Wed","Thu","Fri","Sat","Sun"];

//variable index is the index in list weekDays of s

var index=weekDays.findIndex(function(weekDay){return weekDay==s;});

//use module operator % to get the remainder of the division (index+k)/7

//return the string value of the day

return weekDays[(index+k)%7];
