Check Increasing Trend

Write a Python program to check whether a sequence of numbers has an increasing trend or not.

Sample Solution:

Python Code:

# Define a function named increasing_trend that takes a list of numbers (nums) as an argument.
def increasing_trend(nums):
    # Check if the sorted version of the list is equal to the original list.
    # If the list is sorted, it means the numbers are in increasing order.
    if (sorted(nums) == nums):
        # Return True if the list is in increasing order.
        return True
    else:
        # Return False if the list is not in increasing order.
        return False

# Test the function with different lists of numbers and print the results.

# Test case 1
print(increasing_trend([1,2,3,4]))

# Test case 2
print(increasing_trend([1,2,5,3,4]))

# Test case 3
print(increasing_trend([-1,-2,-3,-4]))

# Test case 4
print(increasing_trend([-4,-3,-2,-1]))

# Test case 5
print(increasing_trend([1,2,3,4,0]))

Sample Output:

True
False
False
True
False

Explanation:

Here is a breakdown of the above Python code:

• Function definition:
• The code defines a function named "increasing_trend()" that takes a list of numbers (nums) as an argument.
• Comparison:
• The function checks if the sorted version of the list is equal to the original list.
• Return Statement:
• If the list is sorted, it means the numbers are in increasing order, and the function returns 'True'. Otherwise, it returns 'False'.
• Test Cases:
• The function is tested with different lists of numbers using print(increasing_trend(...)).
