C語言 題目 怎嚜解題
小妹剛學C語言 不太會解這一題 希望有人能提供解法
Do you know that there are squares within a square. This might seem confusing, but take a look at this.
Suppose you have a square grid of size 5 X 5 completely filled with integers.
You can make three squares from the table above… well there are more but we will consider only concentric squares. The squares are denoted using different fonts.
In this problem you have to find the sum of the numbers of each square.
For the above case the sums are
5 + 3 + 2 + 7 + 9 + 1 + 4 + 5 + 6 + 1 + 1 + 1 + 4 + 5 + 6 + 3 = 63
7 + 4 + 2 + 3 + 4 + 3 + 4 + 5 = 32
2 = 2
There will be several lines in the input file. Each case starts with an integer n(n<=10) that determines the dimension of the square grid. Each of the next n lines will contain n integers each that will fill the square table in row major order. Input is terminated by a case where n == 0.
Each line of output will start with “Case #:” where # is replaced by the case number. Then you have to output ceil(n/2) space separated numbers that will represent the sums from outer to inner. Follow the sample for exact details.
