Translating Number Words to Integer Representation

In the realm of programming, it can be useful to convert written-out number words, such as "one" and "hundred," into their integer counterparts. To address this need, various methods have been developed, including the use of libraries and custom classes.

One approach that leverages a library is the text2int function, which harnesses the power of the numwords dictionary to accomplish the conversion. Upon its first invocation, this dictionary is meticulously assembled, mapping number words to their corresponding integer values and scales.

The core conversion logic commences with splitting the input text string into individual words. As each word is encountered, it is looked up in the numwords dictionary to retrieve its scale and increment. The current numeric representation is then updated accordingly.

For scales greater than 100, a partial result is accumulated, and when a word representing a scale greater than 100 is processed, the partial result is added to the overall result. This process continues until all words in the input text have been processed, resulting in the conversion of the number words into a single integer value.

For instance, when the input text "seven billion one hundred million thirty one thousand three hundred thirty seven" is provided, the text2int function skillfully translates it into the integer 7100031337, demonstrating the effectiveness of this approach.
