Given a binary string, count number of substrings that start and end with 1. For example, if the input string is “00100101”, then there are three substrings “1001”, “100101” and “101”. A Simple Solution is to run two loops. Outer loops picks every 1 as starting point and inner loop searches for ending 1 and increments count whenever it finds 1.&nbsp;Count number of substrings that start and end with 1 in a Binary String: <a href="https://www.geeksforgeeks.org/given-binary-string-count-number-substrings-start-end-1/">https://www.geeksforgeeks.org/given-binary-string-count-number-substrings-start-end-1/</a>

Add Binary Strings | DSA Problem

The idea is to first calculate the length of the string as n and then run a loop n times. In each iteration store ASCII value of character in variable val and then convert it into binary number and store result in array finally print the array in reverse order.Given a string of character the task is to convert each character of a string into the equivalent binary number. Examples :&nbsp; &nbsp; Input : GFG Output : 1000111 1000110 1000111 &nbsp;Input : &nbsp;geeks Output : 1100111 1100101 1100101 1101011 1110011 &nbsp; Convert String into Binary Sequence : <a href="https://www.geeksforgeeks.org/convert-string-binary-sequence/">https://www.geeksforgeeks.org/convert-string-binary-sequence/</a>

Convert String into Binary Sequence

Given a binary array sorted in non-increasing order, count the number of 1’s in it.Examples:Input: arr[] = {1, 1, 0, 0, 0, 0, 0} Output: 2Input: arr[] = {1, 1, 1, 1, 1, 1, 1} Output: 7Input: arr[] = {0, 0, 0, 0, 0, 0, 0} Output: 0Count 1’s in a sorted binary array : <a href="https://www.geeksforgeeks.org/count-1s-sorted-binary-array/">https://www.geeksforgeeks.org/count-1s-sorted-binary-array/</a>

Count 1’s in a sorted binary array

Given string str, return true string follows pattern anbn, i.e., it has a’s followed by b’s such that the number of a’s and b’s are same.Examples: &nbsp;Input : str = "aabb" Output : YesInput : str = "abab" Output : NoInput : str = "aabbb" Output : NoCheck if a string follows a^nb^n pattern or not: <a href="https://www.geeksforgeeks.org/check-string-follows-anbn-pattern-not/">https://www.geeksforgeeks.org/check-string-follows-anbn-pattern-not/</a>

Check if a string follows a^nb^n pattern or not

Given a string consisting only of 1’s and 0’s. In one flip we can change any continuous sequence of this string. Find this minimum number of flips so the string consist of same characters only. Examples:&nbsp; &nbsp;Input : 00011110001110 Output : 2 We need to convert 1's sequence so string consist of all 0's.Input : 010101100011 Output : 4Minimum flips of continuous characters to make all same in a binary string: <a href="https://www.geeksforgeeks.org/min-flips-of-continuous-characters-to-make-all-characters-same-in-a-string/">https://www.geeksforgeeks.org/min-flips-of-continuous-characters-to-make-all-characters-same-in-a-string/</a>

Minimum flips of continuous characters to make all same in a binary string

Given a string of 0 and 1, we need to check that the given string is valid or not. The given string is valid when there is no zero is present in between 1’s. For example, 1111, 0000111110, 1111000 are valid strings but 01010011, 01010, 101 are not.&nbsp; Examples:Input : 100 Output : VALIDInput : 1110001 Output : NOT VALID There is 0 between 1sSuppose we have a string: 01111011110000 Now take two variables say A and B. run a loop for 0 to length of the string and point Ato the first occurrence of 1, after that again run a loop from length of the string to 0and point second variable to the last occurrence of 1.So A = 1 (Position of first ‘1’ is the string) and B = 9 (last occurrence of ‘1’).&nbsp;Now run a loop from A to B and check that ‘0’ is present between 1 or not, if “YES” than set flag to 1 and break the loop, else set flag to 0.In this case flag will set to 1 as the given string is not valid and print “NOT VALID”.Check if a binary string has a 0 between 1s or not : <a href="https://www.geeksforgeeks.org/check-binary-string-0-between-1s-not/">https://www.geeksforgeeks.org/check-binary-string-0-between-1s-not/</a>
