Python

As we all know,python is an easy  to start programming language. Patterns are the most problems given in hiring interviews. So,lets get started fully on number patterns. problem 1 : print the following pattern. sample input 1:            5 sample output 1: 1 2 4 4 8 8 8 16 16 16 16 32 32 32 32 sample input 2: 3 sample output 2: 1 2 4 4 8 8 python code: n=int(input()) k=1 for i in range(0,n):     for j in range(0,i+1):         if j>=1:             print(k,end=' ')         elif j<2:             print(k,end=' ')             k=k*2     print('\n')  problem 2: sample input :4 sample output: 1 3 2 6 5 4 10 9 8 7 python code: n=int(input()) k=1 for i in range(n):     l=[]     h=''     for j in range(i+1): ...

As we all know,python is an easy  to start programming language. coding program are the most problems given in hiring interviews. So,lets get started with basic programs. problem :find the nth element in fibonacci series. sample input:7 sample output:13 python code: def fib(n):     if(n==0):         return 0     elif(n==1):         return 1     else:         return fib(n-1)+fib(n-2) n=int(input('enter an integer value')) for i in range(0,n+1):     x=fib(i) print(x)
