Boost Loop

• use if-else to replace loop
• use if-else to exclude cases and made loop less
• n**0.5 to reduce time to loop
• 能用计算绝对不用复杂数据结构

Questions

• 该loop循环4下还是循环30下？

def ctx(n):
    for i in range(0,n):
        print(i)
        n = n + 1
        if n  == 30:
            return 'finish'

ctx(5)
