 Max Execution Time Limit: 400 millisecs 

 Solution 

 Programming Language: Python 3 Language 

def funcDigit(n):
    x, y, m = 1, 1, {}
    while x <= 10:
        m[x] = y
        y = y + (10 ** x - 10 ** (x - 1)) * x
        x += 1
    for i, j in m.items():
        if n < j:
            break
    i -= 1
    y = m[i]
    return str(10**(i - 1)+(n-y)//i)[(n - y) % i]
n=int(input())
print(funcDigit(n))

Find Generation Gap

PKJ
 Coding Problem Keys   Find Generation Gap   Problem Statement  The family hierarchy is given in N lines. Each lines contains parent and child separated by a space. The program must find the number of generations present between the first and last generation.  Boundary Condition(s)  1 <= N <=100 1 <= Length of parent, child <= 100  Input Format  The first line contains the N. The next N lines contain the percent and child names separated by a space.  Output Format  The first line contains the specified output.  Example Input/Output 1   Input  3 son grandson father son grandfather father  Output  2  Explanation  The first generation member is grandfather. The last generation member is grandson. There are two generations between them (father and son) hence the output is 2.  Example Input/Output 2   Input  6 grandfather father father son1 father son2 son1 gran...
