Summary
Turn an integer into its string representation.
Problem statement
Given an integer, return its string representation. The function should work for positive, zero, and negative integers. Do not add extra whitespace or formatting — just convert using standard string conversion.
Task
Create a function that returns the string form of an integer using Python's conversion.
Examples
Positive integer
Input
convert_int_to_str(42)
Output
"42"
Explanation
The integer 42 becomes the string "42".
Input format
A single integer is passed as the only argument to convert_int_to_str.
Output format
Return the string representation of the integer.
Constraints
- Use Python's built-in conversion; do not implement manual digit assembly. - Input will be a valid integer.
Samples
Sample input 0
convert_int_to_str(-7)
Sample output 0
"-7"
Explanation 0
Negative numbers keep the minus sign in the string.
