Minimum indexed character

 


Easy Accuracy: 50.58% Submissions: 21507 Points: 2

Given a string str and another string patt. Find the first position (considering 0-based indexing) of the character in patt that is present at the minimum index in str.


Example 1:

Input:
str = geeksforgeeks
patt = set
Output: 1
Explanation: e is the character which is
present in given patt "geeksforgeeks"
and is first found in str "set". First Position
of e in str is 1.

Example 2:

Input:
str = adcffaet
patt = onkl
Output: -1
Explanation: There are none of the
characters which is common in patt
and str.


Your Task:
You only need to complete the function minIndexChar() that returns the index of answer in str or returns -1 in case no character of patt is present in str.

Large Factorial of array

You are given an array   A   of integers of length   N . You need to calculate factorial of each number. The answer can be very large, so print it modulo   10 9  + 7 .   Example 1: Input: N = 5 A[] = {0, 1, 2, 3, 4} Output: 1 1 2 6 24 Explanation: Factorial of 0 is 1, factorial of 1 is 1, factorial of 2 is 2,  factorial of 3 is 6 and so on. Example 2: Input: N = 3 A[] = {5, 6, 3} Output: 120 720 6 Explanation: Factorial of 5 is 120, factorial of 6 is 720,  factorial of 3 is 6. Your Task: Complete the function  factorial()  which takes   list  a  and single integer  n , as input parameters and returns a list of factorials of the numbers in the list a.

Value equal to index value

Given an array   Arr   of   N   positive integers. Your task is to find the elements whose value is equal to that of its index value. Example 1: Input: N = 5 Arr[] = {15, 2, 45, 12, 7} Output: 2 Explanation: Only Arr[2] = 2 exists here. Example 2: Input: N = 1 Arr[] = {1} Output: 1 Explanation: Here Arr[1] = 1 exists. Your Task:   You don't need to read input or print anything. Your task is to complete the function  valueEqualToIndex()  which takes the array of integers  arr[]   and  n  as parameters and returns an array of indices where the given conditions are satified. When there is not such element exists then return an empty array of length 0. Expected Time Complexity:  O(N) Expected Auxiliary Space:  O(1) Note : There can be more than one element in the array which have same value as their index. You need to include every such element's index. Follows 1-based indexing of the array. Constraints: 1 ≤ N ≤ 10 5 1 ≤ Arr[i] ≤ 10 6

Largest Element in Array

  Given an array A[] of size n . The task is to find the largest element in it.   Example 1: Input: n = 5 A[] = {1, 8, 7, 56, 90} Output: 90 Explanation: The largest element of given array is 90.   Example 2: Input:   n = 7 A[] = {1, 2, 0, 3, 2, 4, 5} Output: 5 Explanation: The largest element of given array is 5.    def largest( arr, n):     return max(arr) #{ #  Driver Code Starts #Initial Template for Python 3 def main():     T = int(input())     while(T > 0):         n = int(input())         a = [int(x) for x in input().strip().split()]         print(largest(a, n))         T -= 1 if __name__ == "__main__":     main()
