    1716 - Calculate Money in Leetcode Bank.

    Easy

    Hercy wants to save money for his first car. He puts money in the Leetcode bank every day.

    He starts by putting in $1 on Monday, the first day. Every day from Tuesday to Sunday, he will put in $1 more than the day before. On every subsequent Monday, he will put in $1 more than the previous Monday.

    Given n, return the total amount of money he will have in the Leetcode bank at the end of the nth day.

    Example 1:

    Input: n = 4

    Output: 10

    Explanation: After the 4th day, the total is 1 + 2 + 3 + 4 = 10.

    Example 2:

    Input: n = 10

    Output: 37

    Explanation: After the 10th day, the total is (1 + 2 + 3 + 4 + 5 + 6 + 7) + (2 + 3 + 4) = 37. Notice that on the 2nd Monday, Hercy only puts in $2.

    Example 3:

    Input: n = 20

    Output: 96

    Explanation: After the 20th day, the total is (1 + 2 + 3 + 4 + 5 + 6 + 7) + (2 + 3 + 4 + 5 + 6 + 7 + 8) + (3 + 4 + 5 + 6 + 7 + 8) = 96.
