Mips 无法在屏幕上打印数字之间的空白

此代码查找行列式等于零的子矩阵，但不能打印数字之间的空格和行

如何打印行和数字之间的空格

这是完整的代码：

下面是示例代码，演示如何打印两个数字之间的空格。让它适应你的需要

# print number 1
li $a0, 1   # number to print
li $v0, 1   # syscall number for printing integer
syscall

# print space, 32 is ASCII code for space
li $a0, 32
li $v0, 11  # syscall number for printing character
syscall

# print number 2
li $a0, 2
li $v0, 1
syscall
