Container With Most Water in DSA Python - Interactive Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to initialize the left pointer at the start of the list.

DSA Python

left = [1]

Drag options to blanks, or click blank then click option'

A1

Blen(height)

C0

D-1

Attempts:

3 left

💡 Hint

Common Mistakes

Starting left pointer at 1 instead of 0.

Using length of list as starting index.

The left pointer should start at index 0, the beginning of the list.

2fill in blank

medium

Complete the code to initialize the right pointer at the end of the list.

DSA Python

right = [1]

Drag options to blanks, or click blank then click option'

A-1

B0

Clen(height)

Dlen(height) - 1

Attempts:

3 left

💡 Hint

Common Mistakes

Using len(height) as index which is out of range.

Starting right pointer at 0.

The right pointer should start at the last index, which is length minus one.

3fill in blank

hard

Fix the error in the while loop condition to continue until left is less than right.

DSA Python

while [1] < right:

Drag options to blanks, or click blank then click option'

Aright - 1

Bleft

Cleft + 1

Dright

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'right < right' which is always false.

Using 'left + 1 < right' which skips valid comparisons.

The loop should run while left pointer is less than right pointer.

4fill in blank

hard

Fill both blanks to calculate the current area and update max_area if needed.

DSA Python

current_area = (right - left) * min(height[left], height[[1]])
max_area = max(max_area, current_area) if current_area [2] max_area else max_area

Drag options to blanks, or click blank then click option'

Aleft

Bright

C>

D<

Attempts:

3 left

💡 Hint

Common Mistakes

Using height at left pointer without min.

Updating max_area when current_area is smaller.

The height used is the minimum of heights at left and right pointers. Update max_area if current_area is greater.

5fill in blank

hard

Fill all three blanks to move the pointer with smaller height inward.

DSA Python

if height[left] [1] height[right]:
    left [2]= 1
else:
    right [3]= 1

Drag options to blanks, or click blank then click option'

A<

B+

C-

D>

Attempts:

3 left

💡 Hint

Common Mistakes

Moving the wrong pointer based on height comparison.

Using wrong operators for pointer movement.

If height at left is less, move left pointer right by adding 1. Otherwise, move right pointer left by subtracting 1.
