3.Write a Python function to find the maximum and minimum numbers from a sequence of numbers. Note: Do not use built-in functions.

 

def check1(catchlist):

    j=catchlist[0]

    i=int(0)

    for i in range(0,len(catchlist)):

        if(j<=catchlist[i]):

            j=catchlist[i]

    print(j)

def check2(catchlist):

    j=catchlist[0]

    i=int(0)

    for i in range(0,len(catchlist)):

        if(j>=catchlist[i]):

            j=catchlist[i]

    print(j)

list=[2,3,4,5,6,7,9,12]

check1(list)

check2(list)
