Value inside range
Input
clamp(5, 1, 10)
Output
5
5 is between 1 and 10, so clamp returns 5.

Problem statement
Write a function clamp(value, low, high) that returns value constrained to the inclusive interval [low, high]. If value is less than low, return low. If value is greater than high, return high. Otherwise return value. You may assume low <= high.
Task
Implement a function clamp(value, low, high) that returns value adjusted to the inclusive bounds low and high.
Examples
Input format
Three numbers provided as function arguments: clamp(value, low, high). Assume low <= high.
Output format
Return a number (int or float) that lies within [low, high].
Constraints
Numbers are ints or floats. low will be less than or equal to high. Do not use external libraries.
Samples
Sample 1
Input
clamp(-3, 0, 7)
Output
0
Value -3 is below low (0), so return 0.
