Given a number and a digit to remove from that number, maximize the resulting number after the digit has been removed and print it.

/*
From the challenge provided, it is evident that the right-most number should be removed to get the maximum value when the digit is removed.
*/
const removeDigit = (val, digit) => {
  const length = digit.toString().length
  if (length > 1) {
    return console.log(`You can only pass a single digit`)
  }
  
  const str = val.toString()
  const lastIndex = str.lastIndexOf(digit)
  if (lastIndex !== -1) {
    return console.log(`${str.slice(0, lastIndex)}${str.slice(lastIndex + 1)}`) 
  }
  
  console.log(`Digit '${digit}' not found. Return original value of ${val}`)
}

// Testing
removeDigit(23456, 3)
removeDigit(83388833333, 8)
removeDigit(123, 4)
removeDigit(246, 'S')
