Codeforces Problem 1849A - Morning Sandwich

Codeforces problem 1849A, aptly titled "Morning Sandwich," transports participants to a scenario involving the creation of a morning sandwich. The challenge tasks programmers with determining the maximum number of steps required to assemble the sandwich.

Python Solution for Problem 1849A - Morning Sandwich

t = int(input())
for i in range(t):
    a,b,c = map(int,input().split())
    ans = 0
    sum = b+c
    while a>0:
        ans += 1
        if sum!=0 and a!=1:
            ans += 1
            sum -= 1
        else:
            break
        a -= 1
    print(ans)

Explanation of the Python Code

1. Input and Loop: The code initiates by reading an integer `t`, representing the number of test cases. A loop then iterates through the range of test cases specified.

2. Input Acquisition and Initialization: For each test case, the code reads three integers: `a` (total number of ingredients), `b` (initially available ingredients), and `c` (ingredients added during assembly). The variable `ans` is initialized to track the number of steps required.

3. Calculating Total Ingredients: The variable `total` is calculated by summing `b` and `c`, representing the total available ingredients for sandwich assembly.

4. Assembling the Sandwich: A `while` loop iterates as long as there are ingredients available (`a > 0`). Within each iteration, the `ans` is incremented to represent a step. If there are ingredients available in `total` and the remaining ingredients `a` are not equal to 1, an additional step is accounted for. The value of `total` is decremented, simulating ingredient usage. If either condition is not met, the loop is broken.

5. Output Display: The code calculates the maximum number of steps required to assemble the sandwich and prints it as the result.

Conclusion

Competitive programming thrives on fostering effective problem-solving, demonstrated by Codeforces problem 1849A - Morning Sandwich. The Python solution analyzed above empowers programmers to optimize sandwich assembly steps through efficient ingredient utilization. This coding endeavor highlights the significance of loops, conditions, and iterative handling in problem-solving.
