Python Implementation 1-9 array form result 100 for all computational formula examples, python1-9
Problem:
Write one in 1, 2 ,..., 9 (the sequence cannot be changed) insert + or-between numbers or do nothing, so that the calculation result is always 100 of the program and all possibilities are output. For example, 1 + 2 + 34-5 + 67-8 + 9 = 100.

background:Recent projects need to be finished by themselves Excel formulas are parsed and evaluated, and in Java you can use POI to parse an Excel formula and then evaluate it. However, the project needs to support the analysis of the formula JS and Java back-end, so it is necessary to write a set of their own. In fact, the formula parser is not complex on the w

The introduction of WPS Office 2005 has both strong supporters and strong opponents. One of the main reasons for opponents is that many of the previously useful features disappeared in version 2005, such as the insertion formula function.
Indeed, both professional and personal editions do not provide the ability to insert mathematical formulas. This made the math teachers very dissatisfied. However, WPS Text 2005 provides the "Insert Object" function

There are many formulas for calculating pi pai in history, in which Gregory and Leibniz found the following formula:
Pai = 4* (1-1/3+1/5-1/7 ...)
The formula is simple and graceful, but in a bad way, it converges too slowly.
If we rounded to keep its two decimal digits, then:
Cumulative 1 items and are: 4.00
Cumulative 2 items and are: 2.67
Cumulative 3 items and are: 3.47
