Convert number to words
The task is to implement a program that takes a numerical input and converts it into its word representation. The input can be any positive integer up to 19 digits long. The program should be able to handle numbers in the range from 0 to 999,999,999,999,999,999 (nineteen nines).
For instance, if the input is "12345678", the program should output "One Crore Twenty Three Lakh Forty Five Thousand Six Hundred Seventy Eight".
Algorithm
To convert a number into words, we can follow the following algorithm:
- Define arrays to store the word representation of digits, currency names, and multiples of ten.
- Write a recursive function to handle the translation of a given part of the number.
- In the main function, iterate through the digits of the number.
- If the digit is not zero, determine the appropriate translation based on the number of digits remaining and print the corresponding word.
- Continue this process until all digits have been processed.
Pseudocode
function translate(num, length, start):
if length > 0:
if length = 1:
ans = num[start] - '0'
print simple_digit[ans]
translate(num, length - 1, start + 1)
else if length = 2:
if num[start] = '0':
translate(num, length - 1, start + 1)
else:
ans = (num[start] - '0') * 10 + (num[start + 1] - '0')
if ans >= 10 and ans <= 19:
print simple_digit[ans]
else:
ans = num[start] - '0'
print multiplex[ans]
translate(num, length - 1, start + 1)
function printWord(num, length):
if length = 1:
translate(num, 1, 0)
return
counter = 0
digits = length
status = 0
while counter < length and digits > 0:
if num[counter] != '0':
status = 1
if digits = 1:
translate(num, 1, counter)
counter += 1
digits -= 1
else if digits = 2:
translate(num, 2, counter)
counter += 2
digits -= 2
else:
if digits = 3 or digits % 2 = 0:
translate(num, 1, counter)
counter += 1
digits -= 1
print currency[digits]
else:
translate(num, 2, counter)
counter += 2
digits -= 2
print currency[digits]
else:
counter++
digits--
if status = 0:
print "Zero"
function numToWords(num):
length = length(num)
print "Given Number: [" + num + "]"
if length > 19:
print "Number Out of range"
return
printWord(num, length)
Converting a number to words means representing a numerical value using words instead of numerals. For example, the number "123" can be converted to "one hundred and twenty-three" in words. This conversion can be useful in various contexts, such as in financial documents, legal documents, or when writing out a check. It can also be helpful for individuals who have difficulty reading or understanding numbers. The process of converting numbers to words involves determining the value of each digit and then expressing that value in words based on a set of rules for constructing the word form.

Given Number : [86]
Eighty SixExplanation
The algorithm starts by defining arrays to store the word representation of digits, currency names, and multiples of ten. The translate function recursively converts a given part of the number into words. It handles single-digit numbers and two-digit numbers separately. The printWord function iterates through the digits of the number and determines the appropriate translation based on the number of digits remaining. It prints the corresponding word and currency name. Finally, the numToWords function takes an input number, checks its length, and calls printWord to print the word representation of the number.
Let's take an example to understand the execution of the code:
numToWords("12345678")
The given number is "12345678". The printWord function will iterate through each digit and translate it into words:
- Digit '1': Translated to "One" and printed.
- Digit '2': Translated to "Twenty" and printed.
- Digit '3': Translated to "Thirty" and printed.
- Digit '4': Translated to "Forty" and printed.
- Digit '5': Translated to "Fifty" and printed.
- Digit '6': Translated to "Sixty" and printed.
- Digit '7': Translated to "Seventy" and printed.
- Digit '8': Translated to "Eight" and printed.
The printWord function also determines the appropriate currency names based on the number of digits remaining and prints "Crore" and "Lakh" accordingly. The final output will be:
One Crore Twenty Three Lakh Forty Five Thousand Six Hundred Seventy Eight
Time Complexity
The time complexity of the algorithm depends on the number of digits in the input number. Let's denote the number of digits as 'n'. Since the algorithm iterates through each digit only once, the time complexity is O(n). This is because the size of the input number directly affects the number of iterations performed by the algorithm.
