Question 1: The user will enter a list of numbers and a separate number. The program will display the index at which the number is present in the list. If the number is absent, it'll return -1. Do NOT use built-in functions for searching.

l=[]
for a in range (int(input('The length of list should be : '))):
    b=int(input('Enter element '+str(a+1)+': '))
    l.append(b)
c=int(input('Enter element to find the index no. : '))
if c in l:
    for x in range(len(l)):
        if c==l[x]:
            print('The element',c,' is at index',x)
            break
        else:
            continue
else:
    print('1')
The length of list should be : 4 Enter element 1: 1 Enter element 2: 2 Enter element 3: 3 Enter element 4: 4 Enter element to find the index no. : 2 The element 2 is at index 1 or 2 position.
