You are given:
values = {
"db_host": "example.com",
"db_port": 5001
}
{{
and
}}
, for example:
"application is now connecting to {{db_host}}:{{db_port}}"
Implement a function that replaces each placeholder in the template string with the corresponding value from the dictionary. For the example above, the output should be:
"application is now connecting to example.com:5001"
Assume:
Describe your approach and then implement the function in a programming language of your choice.
Now, instead of a single template string, you are given another dictionary where each value is a template string that may contain the same kind of {{key}} placeholders, and you are also given the same values dictionary used for substitution.
Example:
values = {
"db_host": "example.com",
"db_port": 5001
}
templates = {
"conn_msg": "application is now connecting to {{db_host}}:{{db_port}}",
"short_msg": "{{db_host}}:{{db_port}}"
}
Implement a function that takes values and templates and returns a new dictionary where each value in templates has had its placeholders replaced using values.
Explain your algorithm, including its time complexity in terms of:
L
= total length of all template strings
K
= number of distinct keys in the
values
dictionary.
