Word Meaning

• Procurement = a formal word for “buying” or “purchasing,” usually used in business or government.
• Plan = a strategy or arrangement.

So Procurement Plan literally means:

👉 “A plan for how to buy things within a budget.”

Problem (in simple words)

• We have a list of part prices → nums.
• Budget = target.
• We want to buy exactly 2 parts.
• The total cost must be less than or equal to target.
• Question: How many different pairs can we buy?
• Because the number can be very big, return the result modulo 1,000,000,007.

Example 1

nums = [2, 5, 3, 5], target = 6

• Possible pairs:
  • 2 + 3 = 5 ✅
  • all others are too expensive ❌

Answer = 1

Example 2

nums = [2, 2, 1, 9], target = 10
