Don't give me five!

Don't give me five!Codewars

Approach

1. iterate from begin to end

   1. while iterate convert current index(begin) as string and search that '5' exist, if does not exist increase count

   2. increase index(begin)

2. return count

Solution

JavaScript

const dontGiveMeFive = (begin, end) => {
  let count = 0;
  
  while (begin <= end) {
    if (!String(begin).match(/5/)) {
      count += 1;
    }
    begin += 1;
  }
  
  return count;
};
