Finding combinations that sum to a target is useful in budgeting, meal planning, and resource allocation where exact totals are needed.
💼 Career
Backtracking and combination generation are common in coding interviews and algorithm design roles.
Progress0 / 4 steps
1
Create the ingredients array
Create an array called ingredients with these exact numbers: 2, 3, 6, 7
DSA Typescript
Hint

Use square brackets [] to create an array and separate numbers with commas.

2
Set the target sum
Create a variable called target and set it to 7
DSA Typescript
Hint

Use const to create a variable that does not change.

3
Write the findCombinations function
Write a function called findCombinations that takes ingredients and target as parameters and returns an array of all unique combinations of numbers from ingredients that sum exactly to target. Each number can be used only once per combination.
DSA Typescript
Hint

Use a helper function inside findCombinations to explore combinations recursively. Use sorting and skip duplicates to avoid repeated combinations.

4
Print the combinations
Print the result of calling findCombinations(ingredients, target)
DSA Typescript
Hint

Use console.log to print the result of findCombinations(ingredients, target).
