P10549 [AOJ] Insertion Sort
普及
题目描述

Write a program of the Insertion Sort algorithm which sorts a sequence A in ascending order. The algorithm should be based on the following pseudocode:

for i = 1 to A.length-1
key = A[i]
/ insert A[i] into the sorted sequence A[0,...,j-1] /
j = i - 1
while j >= 0 and A[j] > key
A[j+1] = A[j]
j--
A[j+1] = key

Note that, indices for array elements are based on 0-origin.

To illustrate the algorithms, your program should trace intermediate result for each step.

Hint

Template in C

Constraints

1 ≤ N ≤ 100

Input

The first line of the input includes an integer N, the number of elements in the sequence.

In the second line, N elements of the sequence are given separated by a single space.

Output

The output consists of N lines. Please output the intermediate sequence in a line for each step. Elements of the sequence should be separated by single space.
