Find if it is possible to get a ratio from given ranges of costs and quantities in Python
Suppose we have a range of cost from lowCost to upCost and another range of quantity from lowQuant to upQuant, we have to check whether we can find the given ratio r where r=cost/quantity, and lowCost ⇐ cost ⇐ upCost and lowQuant ⇐ quantity ⇐ upQuant.
So, if the input is like lowCost = 2, upCost = 10, lowQuant = 3, upQuant = 9 and r = 3, then the output will be True as the cost = r * quantity = 3 * 3 = 9 where cost is in range [1, 10] and quantity is in [2, 8]
To solve this, we will follow these steps −
for i in range l_quant to u_quant, do
res := i * ratio
if l_cost ⇐ res and res ⇐ u_cost, then
return True
return False
Example
Let us see the following implementation to get better understanding −
def can_we_find_r(l_cost, u_cost, l_quant, u_quant, ratio) : for i in range(l_quant, u_quant + 1) : res = i * ratio if (l_cost <= res and res <= u_cost) : return True return False l_cost = 2 u_cost = 10 l_quant = 3 u_quant = 9 ratio = 3 print(can_we_find_r(l_cost, u_cost,l_quant,u_quant, ratio))
Input
2, 10, 3, 9, 3
Output
True
