Python: Find the minimum even value and its index from a given array of numbers
Python Programming Puzzles: Exercise-46 with Solution
Given an array of numbers representing a branch on a binary tree, write a Python program to find the minimum even value and its index. In the case of a tie, return the smallest index. If there are no even numbers, the answer is [].
Input: [1, 9, 4, 6, 10, 11, 14, 8] Output: Minimum even value and its index of the said array of numbers: [4, 2] Input: [1, 7, 4, 4, 9, 2] Output: Minimum even value and its index of the said array of numbers: [2, 5] Input: [1, 7, 7, 5, 9] Output: Minimum even value and its index of the said array of numbers: []

Sample Solution:
Python Code:

def test(nums):
if any(n % 2 == 0 for n in nums):
return min([v, i] for i, v in enumerate(nums) if v % 2 == 0)
else:
return []
nums = [1, 9, 4, 6, 10, 11, 14, 8]
print("Original list:")
print(nums)
print("Minimum even value and its index of the said array of numbers:")
print(test(nums))
nums = [1, 7, 4, 4, 9, 2]
print("Original list:")
print(nums)
print("Minimum even value and its index of the said array of numbers:")
print(test(nums))
nums = [1, 7, 7, 5, 9]
print("Original list:")
print(nums)
print("Minimum even value and its index of the said array of numbers:")
print(test(nums))
Sample Output:
Original list: [1, 9, 4, 6, 10, 11, 14, 8] Minimum even value and its index of the said array of numbers: [4, 2] Original list: [1, 7, 4, 4, 9, 2] Minimum even value and its index of the said array of numbers: [2, 5] Original list: [1, 7, 7, 5, 9] Minimum even value and its index of the said array of numbers: []

Clamps num within the inclusive range specified by the boundary values x and y:
Example:
def tips_clamp_num(num,x,y): return max(min(num, max(x, y)), min(x, y)) print(tips_clamp_num(2, 4, 6)) print(tips_clamp_num(1, -1, -6))
Output:
4 -1
