Hello Programmers In this post, you will know how to solve the ATM Codechef Solution.
One more thing to add, don’t directly look for the solutions, first try to solve the problems of Codechef by yourself. If you find any difficulty after trying several times, then you can look for solutions.
Problem
Pooja would like to withdraw X $US from an ATM. The cash machine will only accept the transaction if X is a multiple of 5, and Pooja’s account balance has enough cash to perform the withdrawal transaction (including bank charges). For each successful withdrawal the bank charges 0.50 $US. Calculate Pooja’s account balance after an attempted transaction.
Input
Positive integer 0 < X <= 2000 – the amount of cash which Pooja wishes to withdraw.
Non-negative number 0<= Y <= 2000 with two digits of precision – Pooja’s initial account balance.
Output
Output the account balance after the attempted transaction, given as a number with two digits of precision. If there is not enough money in the account to complete the transaction, output the current bank balance.
Example – Successful Transaction
Input:
30 120.00
Output:
89.50
Example – Incorrect Withdrawal Amount (not multiple of 5)
Input:
42 120.00
Output:
120.00
Example – Insufficient Funds
Input:
300 120.00
Output:
120.00
ATM CodeChef Solutions in Python
try:
x,y = map(float, input().split())
if x <= y-0.5 and x % 5==0:
print("%.2f"%(y-x-0.50))
else:
print("%.2f"%y)
except:
pass
