Akash and Missing Class Solution Codechef

Akash loves going to school, but not on weekends.

A week consists of 7 days (Monday to Sunday). Akash takes a leave every Saturday.

If a month consists of N days and the first-day of the month is Monday, find the number of days Akash would take a leave in the whole month.

Input Format

  • First line will contain T, the number of test cases. Then the test cases follow.
  • Each test case contains a single line of input, one integer N – the number of days in the month.

Output Format

For each test case, output in a single line, the number of days Akash would take a leave in the whole month.

Constraints

  • 1≤T≤100
  • 1≤N≤10^9

Subtasks

  • Subtask 1 (30 points) : 1≤N≤100
  • Subtask 2 (70 points) : Original Constraints

Explanation

Test case 1: The month consists of 5 days (Monday, Tuesday, Wednesday, Thursday, and Friday). Since there are no Saturdays, Akash would go to school every day. Thus, he takes a leave for 0 days.

Test case 2: The month consists of 6 days (Monday, Tuesday, Wednesday, Thursday, Friday, Saturday). Akash takes a leave only on Saturday. Thus, he takes a leave for 1 day.

Test case 3: The month consists of 8 days (Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday, Monday). Akash takes a leave only on Saturday. Thus, he takes a leave for 1 day.
