Show how to construct a flowchart

A bank charges RM20 per month plus the following check fees for a commercial checking account RM0.50 each for fewer than 10 checks RM0.40 each for 10-19 checks RM0.30 each for 20-29 checks RM0.20 each for 30 or more checks The bank also charges an extra RM25 if the balance of the account falls below RM500 (before any check fee are applied). Draw a flowchart and write a program that asks for the beginning balance and the number of checks written. Compute and display the bank's service fees for the month. Input validation: Do not accept a negative value for the number of checks written. lf a negative value is given for the beginning balance display an urgent message indicating the account is overdrawn
