How to print all sequences of sum equal to X?
1) If current sum is equal to x, then print current sequence. 2) Place all possible numbers from 1 to x-curr_sum numbers at curr_idx in array. Here curr_sum is sum of current elements in arr []. After placing a number, recur for curr_sum + number and curr_idx+1.
How to print all possible consecutive numbers with Sum n?
So we start from start = 1 till end = N/2 and check for every consecutive sequence whether it adds up to N or not. If it is then we print that sequence and start looking for the next sequence by incrementing start point. In the above solution, we keep recalculating sums from start to end, which results in O (N^2) worst-case time complexity.
Are there any consecutive numbers that add up to N?
The task is to print all possible consecutive numbers that add up to N. Recommended: Please try your approach on {IDE} first, before moving on to the solution. One important fact is we can not find consecutive numbers above N/2 that adds up to N, because N/2 + (N/2 + 1) would be more than N.
How to find all possible combinations of numbers?
How would you go about testing all possible combinations of additions from a given set N of numbers so they add up to a given final number? Set of numbers to add: N = {1,5,22,15,0,…} This problem can be solved with a recursive combinations of all possible sums filtering out those that reach the target. Here is the algorithm in Python:
How to find all subsequences with sum equal to K?
Given an array arr [] of length N and a number K, the task is to find all the subsequences of the array whose sum of elements is K Recommended: Please try your approach on {IDE} first, before moving on to the solution.
How to find sub array whose sum is equal to a given number?
To find continuous sub array whose sum is equal to a given number − Iterate through the array. At each element add the next n elements one by one, when the sum equals to the required value print the sub array.
How to calculate the sum of the digits of a given number?
1. Add another variable “Val” to the function and initialize it to ( val = 0 ) 2. On every call to the function add the mod value (n%10) to the variable as “ (n%10)+val” which is the last digit in n. Along with pass the variable n as n/10.
