Q.2.

Given a string as displayed in Input below, find the number of alphabetic letters and number of

decimal digits in that string as displayed in the output:

Input: 12abc 12

Output: Alphabetic letters = 3, Decimal_digits = 4

Q.3.

Given an array of positive integers. All numbers occur even number of times except onc

number, which occurs odd number of times. Find the number in On) time & constant space.

For example if input array is arr = {1, 2, 3, 2, 3, 1,

3) then output would be

3.

Q.4.

Write a program to print all the LEADERS in the array. An element is leader if it is greater than

all the elements to its right side. And the rightmost element is always a leader. For example in

the array {16, 17, 4, 3, 5, 2}, leaders are 17, 5 and

2.

Q.5.

Given a string, count number of words in it. Following characters separates the words: space

(' ') or new line ('In') or tab ("It') or a combination of these.

Q. 6.

Write a Program to find area of a triangle. For example if input would be a = 5, b = 7, c = 8

then output would be area of a triangle as 17.320508. Area of a triangle can simply be

evaluated using following formula as Area = sqrts* (s-a)*(s-b)"(S:c)) where a, b and c arc

lengths of sides of triangle and s = (a+b+c)/2.
