在复习循环的时候，总有99乘法表，总结一下用不同语言实现的代码
1.java
public class M99Test {
public static void main(String[] args) {
m99();
}
public static void m99() {
for (int i = 1; i <= 9; i++) {
for (int j = 1; j <= i; j++) {
System.out.print(j + "×" + i + "=" + i * j + "\t");
}
System.out.println();
}
}
}2.Js

str = str + j + "×" + i + "=" + m + "\t";
}
str += "\n";
}
console.log(str);

void mutil99() {
for (int i = 1; i < 10; i++) {
for (int j = 1; j <= i; j++) {
printf("%d×%d=%d\t", j, i, j * i);
}
printf("\n");
}
}4.Python
#for循环实现
for i in range(1,10):
for j in range(1,10):
if(i>=j):
print("%d×%d=%d"%(j,i,j*i),end="\t")
print("\n")#while循环实现99乘法表
i = 1
while i<10:
j = 1
while j<=i:
print("%d×%d=%d" %(j,i,j*i),end='\t')
# print(f"{j}×{i}={j*i}\t",end='')也可以
j += 1
print('\n')
i += 1
